Hi,

Thanks for reply.

When database services would be stopped, storage admin will migrade data from source san to target san and map the LUNS.

a)Do I require to deattach database from source?

Since database is down and all MDF and LDF files would be shifted to new LUNS, can i attach them in target without de-attach in source?

b)Secondly, any special considerations w.r.t. system databases(master,model,msdb,tempdb)?

c) When I will install new sql server in target, Do i have to create new databases or simply attach the identified mdf/ldf files including system databases for different databases mapped in LUNs ?

Regards,

Yasir
