Good day Experts


We are in the process of upgrading our current SAN Storage (EMC CX500’s Fiber Channel) to our new SAN Storage Dell EqualLogic ISCSI SAN) we will be moving SQL Server 2000 (standalone),  SQL Server 2005(standalone and cluster), SQL Server 2008 R2(cluster)  over to our new SAN.  

I would like to start with instances on my standalone server before moving on to  our clusters.  These are not that critical and could be used for testing.  The two instances on this Microsoft Windows Server 2003 R2 Enterprise x64 Edition are SSMSQLWHS and SSMSQLWHS/TEST

Test Data (T) – SSMSQLWHS/TEST - current drives
Test Logs (U) – SSMSQLWHS/TEST - current drives
New T Drive Test Data (F) -  SSMSQLWHS/TEST - new drive provided by server admin
New U Drive Test Logs (G)  - SSMSQLWHS/TEST - - new drive provided by server admin

Can you please provide me with a step by step plan on how to move SQL Server 2005 over to our new SAN.  This will be my first SAN migration and I want to make sure that I am not missing anything

Thank you everyone for your time today

Add the iscsi LUN for the standard instance to the server.
Are both user and system databases have to be relocated or just the user databases?
Ms has documentation on how to relocate system databases.
You can modify the install, altering the path where the databases should be.

Similar process for the cluster instance that you have to get the LUNs and add hem as a resource to the cluster, and then transition the configuration to match.

It would be simpler if you are migrating from the FC San and are setting up new systems since you could use mirroring and log shipping to get the data from the current to the new servers setup.

Thank you for your reply, we are relocating only user databases.  What I really wanted to know was the steps used to migrate to the new drives.  example

(1) take sql server services offline
(2) use robocopy to copy .mdf & .ldf files to new drives  (or another method)
(3) and so on......................

Thanks
