Update Globallist.xml manually

Hello,

I have this situation. One SEPM console with servers, another SEPM console with computers. I have the same LU policy on both to use the srevers as GUPs. This was working ok until one day, all the clients stop using GUPs and the sylink debug throw the following message:

01/17 11:02:50.807 [4328] [Content]<LUThreadProc>GUP address is empty.. No more GUP to use - maybe all of them may have failed.. Backoff/ or switch to SEPM are the options.

The file Globallist.xml is empty indeed on the SEPM where the computers are, but is ok on the other SEPM where the servers are.

Two questions:

Is there any chance that this architecture works?

Can I manually change the globallist file?

Thanks

Regards
