[Gluster-users] How safe are major version upgrades?

[Hu Bert]

Hi,
we have 2 replicate-3 systems, and i upgraded both online from 5.12 to
6.8 and then to 7.6. No (big) problems here, upgrade took between 10
to 20 minutes (wait until healing is done) - but no geo replication,
so i can't say anything about that part.

Best regards,
Hubert
