Issue plesk migration

[SFonoyet]

Server operating system version

os_Ubuntu 20.04

Plesk version and microupdate number

v18.0.73_build1800251009.17

Hello,

I am trying to replace an old Plesk server with a new one, both in different vlans on the same network (I am changing the hypervisor from vmware to virtuozzo)
I have both Plesk up and running.
The old server is a all in one server installation, the new server have the database and fileserver decentralized
The old server is a Plesk Obsidian v18.0.73_build1800251009.17 os_Ubuntu 20.04
The new server is a Plesk Obsidian v18.0.73_build1800251009.17 os_Ubuntu 24.04
As database both use MariaDB old one version 10.3.39 and the new 12.0.2
The old server has a "Web Pro Edition" 30 domains license, the new one has the 1-month trial license that comes with the installation, when I finish the migration, I will move the license from the old to the new.

When I tried the migration extension I got this error:

Failed to generate migration list file
Cause: Command execution failed on the local server with non-zero exit code.
command: MYSQL_PWD="$(cat /etc/psa/.psa.shadow)" /usr/bin/mariadb --defaults-file=/etc/mysql/my.cnf --silent --skip-column-names -u admin psa -e 'SHOW VARIABLES LIKE '"'"'socket'"'"''
exit code: 1
stdout:
stderr: ERROR 1698 (28000): Access denied for user 'admin'@'localhost'

That is a critical error, migration was stopped.

I can run the command manually from the new server with the credentials i configured on the migration extension:

root@gallant-williams:/home/ubuntu# ssh root@192.*.*.26
root@192.*.*.26's password:
This server is powered by Plesk.
Run the 'plesk login' command and log in by browsing either of the links received in the output.
Use the 'plesk' command to manage the server. Run 'plesk help' for more info.

root@plesk06:~# MYSQL_PWD="$(cat /etc/psa/.psa.shadow)" /usr/bin/mariadb --defaults-file=/etc/mysql/my.cnf --silent --skip-column-names -u admin psa -e 'SHOW VARIABLES LIKE '"'"'socket'"'"''
socket /run/mysqld/mysqld.sock
root@plesk06:~#

I used some solutions I found around the forum to solve previous problems but i can’t find anything about this one.

Any clues?

@SFonoyet , have you tried the solution from the following article:

• https://support.plesk.com/hc/en-us/...-fails-Access-denied-for-user-admin-localhost

hello,
i skiped that one because I have acces to the database:

root@plesk06:~# MYSQL_PWD=`cat /etc/psa/.psa.shadow` mysql -u admin psa
Reading table information for completion of table and column names
You can turn off this feature to get a quicker startup with -A
