Clarifications on PI 7.0 to PI 7.5 AEX Migration

[former_member238007]

Hi Experts,

We got a requirement with one of our customer to migrate from PI 7.0 to PI 7.5 AEX Java stack alone.

Reason for choosing PI 7.5 AEX is based on licencing and cost associated.

We are planning to go with new installation for PI 7.5 AEX.

Existing landscape has no BPM's.

Clarifications Required:

1. What is the approach we can prefer to migrate, is it a phased manner or single shot migration.

Brief count of Interfaces:

totally around 70+ interfaces to migrate from PI 7.0 to PI 7.5 AEX Java stack.

we have 15+ complex java mappings and few XSLT mappings.

2. Will migartion of JAVA mappings will work or do we need to do any changes to fit in PI 7.5 AEX.

3. ESR object to be exported as tpz file from existing production and should be imported into PI 7.5 AEX ( Any other best practice to be followed, please suggest)

4. Regarding with migrating Integration directory objects, can we still use SAP Directory content migration tool to move existing classic scenarios from PI 7.0 dual stact  to PI 7.5 AEX java stack ICO scenarios

What kind of config is required for this tool to be accessed.

Request your valuable inputs please

Many Thanks,

1. As you have just 70+ scenarios and i feel this is not a big number you can go in one shot instead of phase/wave wise.

2.No need to do any changes in java mapping , you can go ahead and migrate them.

3.ESR -7.0--->Dev PO-7.5--->.....--->Prod 7.5

4.You may use migration tool but note this tool wont migrate the scenarios which doesn't has sender channel/agreement. This has to be done manually.

Regarding the tool check below inks :

HI Manoj,

Can you please share some experiences and pain areas during migration.

Also I need few inputs like what kind of configurations are required to migrated ID objects from PI 7.0 to PI 7.5 AEX.

Please share some light over here on how new landscape will connect to OLD PI 7.0 landscape.

Secondly I came to know from few discussions that JAVA mappings needs to be compiled once again and should deploy in PI 7.5 AEX, Is it true?

* Are IDOC mappings requires any changes like constants should be mapped with 1 instead of empty space.

You have provided us a valuable inputs. Appreciate you if you can clarify above queries.

Thanks,

Kishore,

Even we are currently under migration process now from 7.1 dual to 7.5 , for which we have done with almost interface go-live successfully and below are the points so far which we discovered so far.

1.for inbound IDOC interfaces you need to map constant '1' to all the attributes(BEGIN,SEGMENT).

2.Migration tool cant be used for interfaces which doesn't has sender channel/agreement you need to do the configuration manually in your new PO system.

3.No need to re-compile java mapping , we didn't re-compile as 7.0 = JDK 1.4 and 7.5 = 1.8 so as you have compiled jars with 1.4 <1.8 there wont be any issues.

4.IDOC_AAE setup configuration need to done for inbound/outbound interfaces , you will find a lots of bogs in SCN on this.

5.SLD migration is usually take care by Basis team

6.in case if you are using any interfaces with see-burger these need to migrated using SAP B2B Addon.
