Migrate EV File System Archiver stubs and content to new server?

Hi

We are using Symantec File System Archiver (Enterprise Vault) on a Windows server.  We would like to migrate all of the stubs from server A to server B.

Is there any documentation around that we can follow?  

We also need to determine if all of the files on server A are stubs or a mixture of physical files and some stubs - can this be done?

Would we need to rehydrate all files then copy the physical files and then archive once at the destination?

I assume we would need to install the FSA agent/client on the destination server also?

Thanks,

Matt
