Can I move data and full text search files to another drive and change the drive letter? My server's G: drive is rapidly running out of space.  It mainly contains data files (*.mdf) for both system and user databases.  The FullText Catalogs also exist on that drive.

IT added a much lager E: drive.

I would like to:


shutdown SQL Server
copy everything from G:\ to E:\
change the G:\ drive to X:\
change the E:\ drive to G:\
reboot


Will that cause any problems with SQL Server?  At the end of the process all of the files will be on the G:\ drive; just not on the original G:\ drive.
I just did something like this with my system databases for a SAN migration and it didn't seem to have any negative impact. Having said that, I tested it in a dev/test environment. Do you have an opportunity to test this in a dev/test environment?

Also, there's not much of a need to reboot. Just stop the services, do the move, and start the services.

One final consideration is that you copy the files appropriately. Managing NTFS permissions issues can be a real pain so use something like XCOPY (which is what I used) or RoboCopy to ensure that you preserve the integrity of those permissions.
