I know that there are some issues with murder on 2.3, but apart from that 2.3 has very nice features like delayed_expunge. Those new features have greatly reduced our server load and speed is much better for our usage style. At least for me, stability was very fine with 2.3.7. > New setup is 2 boxes each with 2 partitions each ~2T. > Idea was that partitions 1-2 go to server1, and 3-4 to > server2.

Using rsync is even worse if you are using single instance store and therefore want to preserve hardlinks. However, I think rsync is still the best tool for the job. > I though I will copy mailfiles and then reconstruct > mailboxes.db on each server, but > reconstruct -m > reconstructing mailboxes.db currently not supported > :(( > > All auth is done in sql, so no problems migrating that. > > Should we dump mailboxes.db file, parse with some script to > split it in 2, and then reconstruct on each server? That's what I recommend. Dump it to text, split it and import. That way you get clean new mailboxes db files. > > And what would be best way for quotas?
