Reindls close, but he omitted the fact that if changing IP, you better shorten the TTL to about 5 mins - 24 hours before you do anything, assuming your default DNS TTL if 24 hrs as most are, if you use longer, than you need to wait that time. then after a few hours after the change if everythings good, reset your TTL back to 86400 or 1D On 2/11/15, Reindl Harald <h.reindl at thelounge.net> wrote:> > Am 10.02.2015 um 16:35 schrieb The Doctor: >> Quick question. >> >> We are using both IMAP and POP#. >> >> Question : >> how can you avoid retrieving an e-mail that has been already retrieved? > > by just rsync the complete data from the old to the new server > > * first rsync hot while servicers running > * stop services > * second rsync only transfer the differences > * DNS and/or IP change > * start servcies on the new server > > the client don't know anything about that > > >
