    Hello ,

    We are following https://documentation.commvault.com/commvault/v11/article?p=9302.htm to migrate from existing  media to new media agent. Migrating Global dedupe and index can be done through this process . To Migrate the disk library, how can we specify a destination library (s3 bucket).

    Please share us the steps to migrate from disk to s3.

    You can do it this way:

    1. configure new global dedupe storage policy using your new S3 bucket and MA
    2. configure new secondary copies in your existing storage policies pointing to your new S3 dedupe storage
    3. run aux-copy
    4. disable backup activity and promote S3 secondary copies as primary copies
    5. re-enable backup activity
    6. delete you old copies from storage policies
    Using these steps your storage policy copies will honour 512KB block insted of 128KB.
    Index will be rebuilt directly from backup data.

    Thank you .


    Sorry for the delay in response .


    Can we directly migrate from SAN LUN to ECS share (Initially we thought  we cannot migrate from SAN to ECS directly ) Now our ECS team has preseted  ECS  as share .

    Is it a feasible soultion to move mount directly to ECS share .

    Hi Spiker, good question. The difficulty here disk library and cloud library file/object structure are similar, but they are not the same. It would also be a very risky migration because the chunk metadata includes information about which storage policy, archive file and volume identifiers - which must match the CommServe DB that were pointing to the Disk Library.  The answer euMike provided is the best one.
