Can't migrate clients to another SEP domain

Hello,

I tried to move SEP clients from one domain to an other using these steps :

https://www.symantec.com/connect/forums/moving-cli...

I exported SyLink.xml file, stopped smc, replaced the SyLink.xml file with the one I've just exported, and restarted smc.

But when I look SEPM console, my client never appear. When I look on SEP client, it is connected but still using the old domain and group tree.

I tried to import Communication file using SEP client GUI. Every thing said to me that was OK, but no changes.

I finally tried to use SyLinkDrop exporting package from SEPM Console. Evreything is OK, return code is 0 with successfull message, but no changes.

Is there anything I missed ?

Have you any idea about the reason I'm unsuccessfull ?

Thanks.
