How to change Instance Number of an existing 4.6C System ?

[Former Member]

My customer has DEV and QAS systems running in separated boxes and having the same instance number of 00. Now I'm consolidating these two SIDs into a new box. So, I need to change the instance number of one of them.

I found note 127351 on how to do this but noticed that the note only applies up to release 4.0B. Not sure if it still is valid for 4.6C.

I'd appreciate your help on how to do this.

Thanks in advance.

Hi Satid,

if you want to move 2 systems of 2 boxes to 1 box, you have to copy at least one system anyway and therefore need to change the hostname of that system.

If you are doing this, this is a homogenious systemcopy which could be run with R3setup as described in the SAP documentation. I'm using an bit easier approach with more or less just savlib/rstlib - if you are interested, I could mail this to you.

With a homogenious systemcopy or my approach you have to "re-decide" for the instance number - so this is just no problem at all.

For example if you want to change the instance number from 00 to 02

do the following procedure as follows:

Rename FOlder of instance name DVEBMGS00 to DVEBMGS02 on CI.

in /usr/sap/<SID>/SYS/profile, rename Start profile and Instance profile.

Then open the content of renamed Start profile and seacrh 00 in all the lines and change to 02.

Also edit the instance profile and change from 00 to 02.

Lastly edit DEFAULT.PFL and change the instance number from 00 to 02.

Be sure before changing the instance number, always backup or copy three profiles to some other folder.
