I have some questions during preparation to migrate to the new MA.
Before all this change I Matainance MA or Disable it. Which will be better ?
I wanna replace OLD MA to new MA. So I use robocopy with /mirror and /copyall to copy DDB and Index( on the same place and disk letter).
Then I turn off OLD MA and on NEW MA change IP and name (the same that have OLD),
The next step is to install Commvault MA on NEW, and at the end of the installation, agree that there is a Client with the same name and replace it.
Do you think it should work?
And if something is wrong I have old Ma and can go back to him,

hello @Zawro
Don't worry I've done this many times and it works. However, to be on the safe side, I recommend manually saving your DDB (this is a method I used in the past).
to do this
Open yourmedia agent and navigate to the DD partition.
You'll find the CVSIDB directory there. Copy all the contents of this directory to a shared folder or an out-of-place location where you can easily access it later.
This will ensure you have a copy in case anything goes wrong during your migration. If needed, you can restore the DDB files from the out-of-place location to the new DDB location. Then, from the console, choose MOVE DDB PARTITION and select the option Change config only(as shown in the screenshot below).
Let me know if you run into any issues!

It’s generally recommended to disable the old MA before starting the migration. This ensures that backup, restore, or auxiliary copy operations are stopped, but administrative tasks can still be carried out. If you put the MA into disable mode, it will stop the all operations, which is helpful during the transition.
2-Manual Migration build your new MA with a new hostname/client name, and add it in Commvault. Migrate your data (such as storage and DDB) to the new MA. Once the migration is complete, decommission the old Windows MA.
Regarding the Index by default, the index cache is located in the MA installation dir . There is no need to copy the contents of the index cache manually, as the new MA can perform index restores directly from the media once the data is migrated.
Let me know if you have any further questions.
