Upgrade of CRM 5.0 abap and java

Hi,

I have to upgrade CRM 5.0 to CRM 7.0 with EhP1. In my system landscape, CRM 5.0 ABAP (CRA) and CRM 5.0 Java (CRJ) are installed on different servers. CRJ is a portal available for end user for which CRA is acting as backend server and database. I have experienced that when we install CRM 7.0, installer automatically creates 2 seperate instances each for abap and java. I am not able to presume what exactly will happen in this kind of upgrade. My doubts are:

1. Will this upgrade CRA (abap) and CRJ (java) seperately on different server? and i connect them as i am doing currently (CRA being the UME for CRJ)?

2. While upgrading CRA, upgrade tool will ask the path of CRJ and both the instance will be upgraded simultaneously. And CRJ will behave as web ui instance after upgrade.

3. CRA will be upgraded and a new instance for WebUI will be created (let us call it CRW) and i will connect CRW with CRJ for all practical purposes? where CRJ will act as portal for CRW.

Kindly help.

Thanks.

    Hi,

    > 1. Will this upgrade CRA (abap) and CRJ (java) seperately on different server? and i connect them as i am doing currently (CRA being the UME for CRJ)?

    Yes. You need to upgrade both the servers separately. You need not to reconnect it as both the systems are already connected with each other.

    No, new instance will be created. You need to upgrade CRA and CRJ separately. WEBUI will be automatically upgraded.

    Thanks
