Resolution
- Connect via SSH
- Create directory manually and set valid ownership and permissions:
In Debian/Ubuntu:
# mkdir /opt/psa/var/modules/panel-migrator/sessions
# chown psaadm:root /opt/psa/var/modules/panel-migrator/sessions
# chmod 0750 /opt/psa/var/modules/panel-migrator/sessionsIn CentOS/RedHat:
# mkdir /usr/local/psa/var/modules/panel-migrator/sessions
# chown psaadm:root /usr/local/psa/var/modules/panel-migrator/sessions
# chmod 0750 /usr/local/psa/var/modules/panel-migrator/sessions

Applied the above solution only to then get the following message:

Hello Kim Harding,
It seems that permissions of
are still incorrect.
Make sure that the file ownership is psaadm:root and permissions are 0750.
Also, make sure that there're no other mechanisms blocking the access to files.
In case this won't help, submit a request to support: https://support.plesk.com/hc/en-us/articles/213608509
