Symptoms
When I use Plesk Migration Manager to migrate data manually I get the following error:
# tail -f /usr/local/psa/admin/logs/panel.log PHP Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 64 bytes) in /usr/local/psa/admin/plib/backup/Conflicts/Detector/ConflictDetector.php on line 495
I get this error after starting import from the migration file /work_dir/dump.xml.
Resolution
There is not enough memory for Plesk Panel php. You need to increase memory_limit for Plesk Panel php in /usr/local/psa/admin/conf/php.ini file up to 512 Mb.
To check if settings were applied correctly you can run
/usr/local/psa/admin/bin/php -info | grep memory_limit memory_limit => 1024 => 1024
Change to:
# memory_limit = 1024M
