Tune and convert is online. Only thing to remember is that you can't convert a volume which is currently in an active RC group.
How did you migrate your 2008 when you needed to reboot during migration? 3PAR to 3PAR with peer motion doesn't require this as long as you're using an ALUA persona (2 or 15) and follow the implemention guide (which states that you enable path verify option in the MPIO options and installs a bunch of KBs).
They were all listed as persona 1 - generic and old HBA drivers. Since we had to reboot anyways to update the drivers we just used that method to finish migration.
