There is any configuration must be backup and restored after upgrading the hub ?After upgrading the existing groups are missing from IM.
Generally speaking no, there's not. The only problem I've had is that there are a number of "performance" parameters that you might tweak that are hard coded in the default cfx file for the hub to return them to the defaults. Problem is that sometimes this is a good thing and sometimes not.
The groups in IM though should not be touched by the hub upgrade.
I have seen cases where IM will open and will fail to retrieve the groups and if you make any changes to IM that prompt it to save changes, you'll then lose your groups. Same can happen if you have multiple IM sessions open with the same account and you make ocnflicting changes between them. WHichever saves secnd will be the configuration that persists.
Groups in IM are stored on your local machine either in the registry or locally.
I wanted to find this out myself how groups are stored since I think editing them myself would be much much quicker. If anyone knows please chime in here. TIA.
