Basic Pleskian
[Plesk 12.0.18 MU #55 on Centos 6.6]
Dear all,
We are planning to do a mass-migration of subscriptions from one dedicated server to the other.
The mass of data (+300 domains) is so big that it takes ~12 hours to transfer all. So by the time the transfer has been done to the destination it is likely that changes have been done on the origin as well.
So we would like to do a second smaller incremental transfer before transferring IP addresses from one server to the other.
We have run some tests with the web tool (Tools and Options --> Migration assistant) to see if changes from the origin are correctly transfered to the destination and the results have not been satisfying:
- A new WordPress installation resulted in the transfer of the new created database but no change on the PHP content.
- New received emails (in a maildir directory) were not synchronized in the destination either.
So if we want to keep with this large transfer approach (instead of doing separate transfers with a small number of subscriptions which would take even more time) we need to find a solution that would at least:
- Incrementally synchronize maildir directories
- Incrementally synchronize web PHP content
- Recopy databases.
The objective is having our customers experience the least down-time during the migration while maintaining the coherence of data.
Therefore WE WOULD LIKE TO ASK:
- Plesk-friendly tools (commandline, API if needed) that would allow an incremental synchronisation between subscriptions.
- rsync invocations or scripts that would achieve that would achieve the same results.
Kind regards,
Miguel Telleria
