We use Symantec Backup Exec to backup our SBS 2003.
How should be manage the backup for both source and destination servers during the 3 weeks long migration?
1) continue backup the SBS 2003, no backup on the new server (SBS 2011)
2) Install Symantec on SBS 2011. run backup on both old and new servers
3) turn off backup on old SBS 2003, only back sbs 2011.
Cheers,
