[former_member182346]

Hi Gurus,

Need you expert comment as I am preparing list :

1 . why to migrate BW 3.5 object like Transfer rule/update rule and ds to new transformation, DTP and new DS ?

2. Is SAP is not going to support BW3.5 objects (as its part of Netweaver2004 - extended support stopped in Apr 2013) ?

3. What are the real benefits of migrating to 7.x ? (details will be appriciated)

Jfyi : I am already going through article

Hi Vinod,

1 . why to migrate BW 3.5 object like Transfer rule/update rule and ds to new transformation, DTP and new DS ?

Because, it is very painful to develop our data flows in 3.5 style Datasource-->Transfer Structure/Transfer rules-->Infosources-->Update rules. You can skip all these steps in BI 7.0 by introducing Transformations and DTPs. This is more straight forward and easy to develop as well as to maintain too.

DTP is a wonderful feature to do error handling, where this concept was not there in 3.5. lot more advantages are there in DTP.

2. Is SAP is not going to support BW3.5 objects (as its part of Netweaver2004 - extended support stopped in Apr 2013) ?

SAP will only support as per the extended support policy. But it is highly recommended to migrate all BW objects at least to BI 7.0, if not to BW 7.3.

3.5 Migrations are no more supported in BW 7.3. You have to migrate them, no choice.

WAD 3.5 is no more supported in BW7.3 GUI version. It is recommended to migrate all web templates at least to WAD 7.0

3. What are the real benefits of migrating to 7.x ? (details will be appriciated)

This has been answered in above replies. When SAP come up with any upgraded versions, all the loop holes in the previous versions will be addressed along with some new features, which will enable our developers as well as our customers with ease of use.

Hi Experts,

again thanks for reply, I am going through the links to generate the final list of key ponits and will post too.

RK,

sorry to say but I guess Adv of DTP & transformation will be good to attract client for migrating to 7.x, but agree that's not enough. I need to find more info which will helpful to validate.

I am thinking of checking:

-Loading time (3x vs 7.x)

Anything else you guys can suggest which will be helpful to support 3.x migration.

As per my knowledge, BW3.5 is netweave2004 component and SAP recently stopped supporting it (even extended support is stopped). SO any issue with transfer/update rule, SAP is not going to support.

Please confirm.

I am confuseed, since client is already migrated to 7.31, the new features are applicable like DSO activation will be improve by 20-40% (

–BW 7.3 package fetch of active table hence faster activation and less lock (20% to 40% fast)

) etc. Although the objects developed in 3.5. There is no migration of DSO ?

Please respond if you can.

Thank-You.

Please check this note for it 1410878.

Hi,

Known fact is that SAP 3.x supporting was stopped  by SAP some how 2012.

Coming 7.X - We have intermediate layer PSA where its mandatory. when we load data from Psa with very less time we load data into target thru DTP.

WDSO(write optimized dso) - Features very useful

Even coming Bex  7.x versions, SQL response time was faster compare to 3.x.

DSO Activation parameter settings at Tx - RSODSO_SETTINGS

Useful concpets at bw 7.x over 3.x

1. Transformation - rule group concept.

2. DSO also included in multi-provider

3. Flexible authorization concepts

4. Real-time data acquisition(RDA)

5.Additional process steps in process chains

Thanks

Please confirm.

I confirm the same. You are 100 % correct. No more support from SAP on 3.5. It has to be maintained by customer itself at his own risk.

Regarding migration of DSO, the data flow can be easily migrated in 7.3. You may create new 7.3 based DSO and load data from your existing DSO to new 7.3 based DSO, so that you can leverage the 7.3 benefits. But this may not be a standard procedure.This is a work around.

Hi Suman,

Thanks for the confirmation.

As Anshu mentioned, that note also not clearly talk abt the BW3.5, whereas refer BEX component of BW3.5.

"

"

Do you mean the upgraded DSO will take more time to activate if I don't migrate it ?

I doubt, I didn't think there is any migration of DSO steps. Even not heard in BW3.5 to BI7 upgrade, if client dont want to migrate the BW 3.5 objects.

I do agree to use the new functionality like Semantically  Partitioned Object, we may need to create a new dso (as you mentioned earlier) but not to achive the activation time improvement.

Please correct me if I am wrong.

Thank-You.

Hi Vinod,

Generally we don't migrate DSos, Cubes to next version s while migrating data flow objects. As you are asking about the new benefits of DSos and Cubes, I gave you a work around.

The activation time should not be a problem. I wonder if there are any FMs to migrate the DSO structures to 7.3 based. DSo activation will be based on several things like data volume, BGDs, RSODSO_SETTINGS , SID generation etc..You need not to worry on this issue.

I suggest you to project about full migration to 7.3 to your client. I hope your client will be convinced.

1 . why to migrate BW 3.5 object like Transfer rule/update rule and ds to new transformation, DTP and new DS ?

With migration to newer version no of objects are reduced. Infosource etc are no more required. DTP/error DTPs can be used. With old objects we observed that with SP upgrade also there are many issues. Maintenance with old object is higher.old authorisation concepts are obsolete and u have to go for analysis authorisations

2. Is SAP is not going to support BW3.5 objects (as its part of Netweaver2004 - extended support stopped in Apr 2013) ?

SAP will stop support after certain time ..and maintenance will become even difficult. you can also take correct recommendation on this from SAP.

3. What are the real benefits of migrating to 7.x ? (details will be appriciated)

performance,new features,HANA compatibility,more user satisfaction to see bigger outputs in lesser time.

Thanks and regards

Hi Experts,

Thanks for reply.

So let me make it clear, I am comfortable with new features of BW7.31, as lots of documents are available) but I need to explain the Client that they should migrate BW objects like 3x flow to 7.x. Although their system is technically upgraded to new BW7.31, they are still using old BW3.5 objects.

BEx components are already migrated to 7. I need to explain them the benefits of MIGRATING to 7.31.

Any help on this will be again helpful.

Anshu Lilhori - You example of LCD to LED was good, can you please throw some light on above as well, based on your experience

Suman Chakravarthy K - I liked :

"DTP is a wonderful feature to do error handling, where this concept was not there in 3.5. lot more advantages are there in DTP." I am looking for such points only which explain what missing if not migrated.

Regarding "But it is highly recommended to migrate all BW objects at least to BI 7.0, if not to BW 7.3." Do you think there will be difference, I don't think there will be any migration from BI7.0 to BW7.x, Please correct me if I am wrong.

As mentioned above (abt qu3. I am looking for real benefits of migrating to 7.x) please enrich us with your experience.

Ramanjaneyulu Korrapati - the second link is helpful, further help is much appreciated.

Thank-You again Experts.

Hi,

Check these links patiently to get some bullet points. You can make a grand sheet by taking points from all replies and finally show to client.

I am working on BI 7.0 and worked on 3.5 as well in the past. I have seen many advantages in using BI 7.0 concepts like Repartitioning of a cube which has data., Remodeling concept, Expert routines which can eliminate whole transformation. You can simply write it to populate data in the target infoprovider.

Hi Vinod,

Reagrding migration, Client may need to check SAP. Once they are happy with new features of higher versions, they will plan to do migration. but in your case its look like reverse.

As said by Anshu, when you see new product in market, if its useful for us without disturbing old product features. then most of them prefer new one.

if you need the exact reason, then there is no exact answer other than higher version advantages.

You can make it note of all higher versions advantages of each concept like Modelling, extraction, bex features and WAD features.

BW 7.3 BW on HANA and BW(7.x) act as database layer for BPC.

Thanks

Hi Vinod,

BW 7.x advantages over 3.x: please check the below link.

Hi,

In generic way if i need to answer i would say change is constant,

Its similar to move from LCD to LED...or from QWERTY to touchpad.

Basically to leverage the new functionality and features packed up in new package.

Also go through this presentation.

http://csc-studentweb.lr.edu/swp/Berg/articles/BIIT_2011/BIIT_Amsterdam/BIIT_2011_Berg_BW_73_upgrade....

Hope this gives some idea.
