Restore Plesk from the corrupted hard disk drive

How do I restore Plesk from the hard disk drive in case if the Operating System is broken and
the HDD with old OS and Plesk is mounted in the new system

Symptoms

My server is broken and operating system does not boot. I mounted the hard drive in the new server and wish to transfer Plesk data to the new server.

Resolution

The best way it is make Plesk backup using PleskX.pl migration agent and restore it on the new server. Follow the steps below:

- mount the old drive, for example to /restore folder. If there are several partitions on the old drive, for example '/' and '/var', they all should be mounted as they were in the old system, so '/' is mounted to /restore/ and '/var/' to '/restore/var/'

- stop all Plesk services in the new system with:
# /etc/init.d/psa stopall


- copy migration agent to the old drive (make sure that there is enought free disk space to perform the dump):
# mkdir /restore/migration
# cp -r /usr/local/psa/PMM/agents/shared/* /usr/local/psa/PMM/agents/PleskX/* /restore/migration


- make chroot to the root folder of the old server (/restore in our case):
# export SHELL=/bin/bash
# chroot /restore


- start MySQL from the old drive in the new chrooted environment:
# /etc/init.d/mysql start


- run migration agent to make Plesk dump:
# cd /migration
# ./PleskX.pl --dump-all -v5


- exit from the chrooted shell after the dump process finished and create
archive folder in the migration directory:
# mkdir /restore/migration/archives


move all files except for dump.xml from /restore/migration/ to /restore/migration/archive folder.

- now you can import data via Plesk CP. Select "Import mode" on
the Server->Migration page and specify "Working directory" where you
put all data, it is /restore/migration/ in this example.
