Move Central Instance to Another Server

Hello expert,

Now we have a distributed system: CI on server 1, DB on server 2. Now we want to move the CI to another server 3 without change the DB server.

We get some information from link Move the central instance to another server in SAP

We have few questions:

1. Can we change the SID of CI with method provided in link?

2. Any other additional steps should we do?

Thanks & Best Regards,
Tong Ning

    Hi Tong,

    Best and fastest method would be to install a new CI on server 3 and scrap existing CI on Server 2.

    Best practise is to maintain the same SID for CI .

    Please plan the downtime for the same.

    Hi Tong,

    You can install a new SAP instance (CI) on the new server as your DB is not moving and is on different host, and replicate important files from your old CI host.

    For eg, the host file, services file, trans directory and some work directory contents.

    Also, if your server on same OS or different ?

    You should check the compatibility of new OS and DB in service market place (PAM).

    For changing SID, please use standard guides and tested WIKI links.

    I can't install the Primary application server from distributed system option.

    It always request the path to profile system /usr/sap/<SID>/SYS/profile but this profile doesn't exist yet.

    How can I install this PAS ?

    Many Thanks
