Not sure exactly what you are asking. Are you moving data from internal drives to a SAN? Is the server clustered or a standalone install? What version of SQL Server?

You can move all paths to the SAN storage if you wish, just ensure you update any path dependencies within sql srever.
For example log path locations for sql agent jobs, etc and the full text default location

If you want the redundant storage that a SAN gives you, yes. If you want faster performance for the system databases, you might consider local storage. Everything is a tradeoff.

Unless its an FCI then you are required to use shared storage not local

100% true. But, you probably wouldn't be asking about where to put storage if you had no choice in the matter.

Sure, about the only time is when migrating data between LUNs

I store them on local drives and make sure they are backed up each night. Keeping them on a local drive, other than the OS drive is still better.

Thanks

Its perfectly viable to use consolidated\shared storage, certainly makes storage management easier.
Having the system databases on local disk means that if you lose the San sql will likely stay online but then what good is this if you have lost all user dbs?
