Couple questions about migration, can't find the information nowhere.

Closed this issue · 4 comments

  • When the migration is in progress do I need to stop read write to my old cluster?

  • When the migration is done can I just connect to that new cluster and continue using it?
    I mean all the indexes will be in place and new writing will be continuing to the same (new) indexes?

  • Can I stop the migration progress any time? can it somehow damage my old cluster/indexes?
    Thank for the help.

  1. The data was snapshotted before the migration, so the further writes won't be migrated after the job started
  2. Sure, why not?
  3. You can stop it anytime, old cluster won't affect at all

Thank you for your quick response.
about questions 2 and 3 I understood.
about the first question a meant
lest assume I don't care about new data.
I just want to know do I need to stop writing to a cluster for the time of copy process? or I can just start the copy process unrelated to the status of my old cluster?
