Log Files

If you faced issues migrating the server, website, or mailbox content,
you can search for information to help you with troubleshooting in the
log files.

Migration log files are accessed via the CLI. You can also view server
migration logs in the Plesk interface.

For each started migration, Plesk creates two log files:

info.log contains general information about the migration.
debug.log contains the specific calls of Plesk utilities, API
requests, and other technical information that can help you identify
the migration step on which the issue occurred.

If you face an error during migration, search the info.log file
for clues first. If the information you find is not enough, read
the debug.log for more technical details. If the root cause of the
issue is still unclear, contact Plesk support.

Viewing Logs via the CLI

Depending on what you migrate, logs are stored in:

Server migration:
- (Plesk for
  Linux) /usr/local/psa/var/modules/panel-migrator/sessions/YYYYMMddHHmmss
- (Plesk for
  Windows) %plesk_dir%varmodulespanel-migratorsessionsYYYYMMddHHmmss
  
  Where YYYYMMddHHmmss shows the date and time when the
  migration was started.
Website importing:
- (Plesk for
  Linux) /usr/local/psa/var/modules/site-import/sessions/site-migration-<domain-id>
- (Plesk for
  Windows) %plesk_dir%varmodulessite-importsessionssite-migration-<domain-id>
  
  Where domain-id is the domain ID.
Mail importing:
- (Plesk for
  Linux) /usr/local/psa/var/modules/site-import/sessions/mail-migration-<domain-id>
- (Plesk for
  Windows) %plesk_dir%varmodulessite-importsessionsmail-migration-<domain-id>
  
  Where domain-id is the domain ID.

Viewing Logs in the Plesk Interface

To view server migration logs from the Plesk Interface, go to
Extensions > Plesk Migrator, click the migration name, and then
go to the “Log” tab. Here you can download the info log and the debug
log, and also view both logs in real time.

By default, Plesk shows only messages from the info log. To see messages
from the debug log as well, select the corresponding checkbox.

By default, messages from logs are collapsed in a tree view. To make
reading log messages in real time more convenient, you can enable auto
scroll and choose to expand the tree automatically. To do so, select the
corresponding checkboxes.

You can also search for keywords in logs. To highlight a keyword, click
Highlight. To see only messages that contain a keyword, click
Filter.
