Verify Zoning 

Check dual connectivity ( San -Switch end )

Reconfigure cluster lock disk on new Storage ................CRITICAL

Ensure Application & DB shutdown before migration .

How are you migrating , any tool ? We used openmigrator tool from EMC .

I wanted to know the precaution which we need to take care from the OS perspective.
