Steps

How do I restore Parallels Plesk from a hard disk drive if the Operating System is broken and the HDD with the old installation is mounted to the new server?

Plesk for Linux/Unix

I mounted the hard drive to a new Plesk server of the same version and want to transfer my Parallels Plesk data to the new server.

Resolution

The best way to do this is to make a Plesk backup using the PleskX.pl migration agent, then restore it on the new server. Follow the steps below:

Mount the old drive, for example to the “/restore” folder. If there are several partitions on the old drive (for example “/” and “/var”), they should all be mounted as they were in the old system (so that “/” is mounted to “/restore/” and “/var/” to “/restore/var/”). USe df to sewe the old drive:

# df -h
# mkdir /restore
# mount /dev/sdb3 /restore

Stop all Plesk services on the new system with this command:

# /etc/init.d/psa stopall

Create a new directory on the old drive and make sure it has the proper permissions (0755):

# mkdir /restore/migration
# chmod 0755 /restore/migration

Copy the migration agent to this location (after making sure there is enough free disk space to perform the dump):

# cp -r /usr/local/psa/PMM/agents/shared/* /usr/local/psa/PMM/agents/PleskX/* /restore/migration 

Ensure that the old drive mounted to “/restore/” has a “/dev” directory with all the required data. Otherwise, copy the data from “/dev” to “/restore/dev”:

# cp -rp /dev/* /restore/dev/

Chroot to the root folder of the old server (“/restore” in our case):

Chroot is an operation that changes the apparent root directory for the current running process and their children. A program that is run in such a modified environment cannot access files and commands outside that environmental directory tree. This modified environment is called a chroot jail.

# export SHELL=/bin/bash
# chroot /restore

Start MySQL from the old drive in the new chrooted environment:

# /etc/init.d/mysqld start 

Run the migration agent to make the Plesk dump:

# cd  /migration
 # chmod +x ./PleskX.pl
 # ./PleskX.pl --dump-all -v5

Exit from the chrooted shell after the dump process is finished…

# exit

and create an archive folder in the migration directory:


# mkdir /restore/migration/archives

Move all files except for dump.xml from “/restore/migration/” to the “/restore/migration/archive” folder.

# mv /restore/migration/* /restore/migration/archive

In Plesk 9.5 and older it is possible to import this data via the Plesk GUI. Go to Home > Migration Manager > Transfer data already processed by the migration agent and located on the local host and specify the dump.xml location (e.g. /restore/migration/dump.xml).

In Plesk 10 and newer the data is restored using the following command:


# /usr/local/psa/bin/pleskrestore --restore ./dump.xml -level server
