How would I move SQL MSSQL.1 and MSSQL.2 location?
First shut down sql server

Then the best option is to robocopy everything from the disk to the new disk with the existing security.

when this is done, remove the old disk, and give the drive letter of that disk to the disk which you robocopied to. After that start SQL Server again.

This way SQL Server will not notice they are now on a new disk.
