How to change instance number

I have a dual stack installation i.e. ABAP+JAVA systems. These are Netweaver 7.0 systems. All of them have default 00 and 01 instance numbers in the landscape. We want to change the instance numbers to avoid port conflicts when moving to virtual servers. Is there any way to do this? I could not find any notes on this.

Any help is highly appreciated.

    Either reinstall the whole system or make a Homogenous System copy to change the instance number.

    Hi ,

    I tried the following procedure once & able to change the instance no::

    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.

    Thanks..

    I don't understand this... as long as they are sitting in different hosts you should not have any issues.

    In any case to move them you'll need to do a homogeneos system copy and then you can change the instance numbers.

    I guess reinstalling Central Instance is the option here.

    Guys,

    Thanks for all your answers.

    I tried to perform the system copy but I am unable to to do in the same host since the SCS is already exists. So the only way the system would work in this situation is perform in a different host. Is that right?

    Thanks,
