The following error is shown when running the backup command for MN:

CT-10-bash-3.00# /usr/local/pem/bin/ -t mn-migration -o POA_backup
Tag:                    mn-migration
Database host:          osscore.provider.tld
Output directory:       POA_backup
Use gzip:               no


ERROR: Following services are installed on MN: (logrotate, logparser, Proftpd, crontabs, bind9). Please uninstall these services from MN and start over the backup procedure.


Migration precheck uses the following SQL query to check if there are any services present on the management node which must be removed:

plesk=> SELECT STRING_AGG(name, ', ') FROM services WHERE host_id = 1 AND name NOT IN ('PrivacyProxy');
 logrotate, logparser, crontabs, Proftpd, bind9
(1 row)

Where host_id is id of the management node (usually = 1).


Find these packages in Provider CP under the Hardware nodes -> %OA_MN_hostname% -> Packages tab by name and remove ones which have Type = 'service'.

See the article for other issues related to MN migration.
