Hi Daniel,
Thanks for the reply. As per your recomendations I will follow these steps, please correct me if I am wrong or missed something:
1. Prepare a new server having OS as windows 2008 64bit.
2. MigrateDP from 32 bit to 64 bit using winomnimigrate.
3. upgrade DP from 6.21 to 7.01 on 64bit OS.
Here I have few queries,
1. For my new OS 64bit should I keep teh hostname and IP same as old CM and migrate the DP. Once migration completed remove the old CM from network and bring new 64bit CM in network. Can I do this?
2. I have 3 Solaris clients and 1 Linux clients but no installation server for unix, for upgrading these clients I need to upgrade manually or how to do it?
3. I have one NAS device EMC celerra using as file server and taking backup using NDMP. While upgrading this DP from 32 bit to 64 bit and from 6.21 to 7.01 what I need to do and this device NDMP is supported in 7.01 also or not?
Many thanks for all your support.
Regards,
Syed
