Upgrading to EP6


I got to do a EP5 to EP6 migration.

As per the system landscape .. We have 3 EP5 servers Develoment/QA/Prod.

As per the migration process these 3 servers are source servers.

So for migrating from Ep5 to EP6 do we need a separate 3 servers for EP6 which is the target system?

ELse can we upgrade EP6 over EP5 on the same server.

Please clarify.

    Hi Rudhras,

    Technically the best way to go is to have three separate servers with EP6 installed on them as the target system of the migration.

    That is the best case but not everyone has three extra servers sitting around. First let me say you can't upgrade EP6 over Ep5 on the same server. You have to have both instances (EP5 and EP6) at the same time to do the migration. What you can do if you have enough resources on the hardware is to install an EP6 instance on the EP5 server. Then migrate the EP5 to EP6.

    When you are finished testing the EP6 instance and are happy with the content, you can delete EP5 system. I know of at least a couple of companies who have done this.

    I would mention however that if you do this for you production migration, you could possibly have a long outage of you production system.

    For more info on the migration process check out these two blogs on SDN:

      John thanks for the reply!!.

      Do let me know how we can go abt to install an EP6 instance on the EP5 server.

      The pre-requisite for both the EP5/6 are different right from the JDK to the Database versions...

      I have both Database & EP running on the same server. For instance if i want to install EP6 then i have to instal ORACLE 9x version on the same server. NOw I have 2 oracle version and also the JDK version...

      Kindly let me know the methodology u mentioned is possible in my case???

    Hi Rudhras,

    You are correct, you have to install the necessary versions of the DB and JDK that are required by EP6. That is why I mentioned that you have to make sure your have enough resources on the box to support all the software you have to run.

    Just a hint if you choose to put them both on one box. Make sure when you are doing the NetWeaver install that you choose the custom install option instead of taking the default. The default will provide default parameters for a number of the options (like ports). If you use the default, you will possibly run into conflicts with your EP5 portal. If you choose custom, you will have the opportunity to specify all the parameters needed during installation.

    One more migration method you may want to consider is if you have one new box to install the NetWeaver portal there. Then migrate your Dev system to it. When you are happy with the migration, wipe out your old EP5 dev system and install a new NW portal there. Migrate your QA to that one. When finished delete the EP5 QA and then repeat the process for Prod.

    Hope this helps
