I have two Suse servers with Idm 3.51 and wish to migrate them to Idm 3.6.

I would like to have Idm 3.51 to fall back on just in case, I was
planning on this scenario

1) Install a third Suse server and add to the driver set
2) Install Idm 3.6 on the new server
3) Move some drivers over to the new server
4) I can move drivers between Idm 3.51 and Idm 3.6 as long as I do not
upgrade the driver. Is this correct?

Am I missing something?
