This error is usually caused by backup failure on the source server.
To troubleshoot the issue, use the following steps:
Upload the proper migration agent and its modules to the source server. For example, if you are transferring data from a Parallels Plesk server, you need to upload these files:
Use the following command to copy the agent and its modules to the source server:
destination ~# scp -r /usr/local/psa/PMM/agents/shared/* /usr/local/psa/PMM/agents/PleskX/* root@source:/temporary_migration_directory/
Log in to the source server and go to the /temporary_migration_directory. Then, run:
temporary_migration_directory ~# chmod 755 PleskX.pl
temporary_migration_directory ~# ./PleskX.pl -da -co -vvvvvv >> migration.log 2>&1
