Yes. I plan to allow tying together two such prefixes in a future release, but I suggest this is the best option for now. > 2.

You should use a new prefix for all of the above, otherwise you risk confusing and dangerous WAL overwriting. > 4. What should I prune? After you are satisfied with the failover for a little while, you can delete the old prefix in its entirety. Does that all seem reasonable? -- You received this message because you are subscribed to the Google Groups "wal-e" group.
