PLESK_ERROR: Can't open perl script "ExecutePleskSQL.pl": no such file or directory
The following error appears in info.log in Tools & Settings > Migration & Transfer Agent > open the session > Logs tab:
CONFIG_TEXT: Execute command on the source server 'source' (203.0.113.2): cd /root/plesk_migrator/plesk_migrator-g409xv9yhlou4klndktp7xiaajptcd2z/pmm_agent; /usr/bin/perl ExecutePleskSQL.pl
Can't open perl script "ExecutePleskSQL.pl": no such file or directory
The directory from the error message exists on the source server and has correct permissions:
# ls -l /root/plesk_migrator/plesk_migrator-g409xv9yhlou4klndktp7xiaajptcd2z
drwx------ 2 root root 4096 Dec 23 12:37 plesk_migrator-g409xv9yhlou4klndktp7xiaajptcd2z
This is a Plesk bug PMT-4216 that will be fixed in future product updates. It may appear when Plesk Agent is deployed in two threads at one time. This is a reliability issue, it should not appear again on the same server.
Just restart the migration session.
