Confirm if account migration still in progress

Using the cPanel copy multiple accounts feature, if our browser tab is closed:

• Only the current migration is finished, other scheduled migrations will not be performed?
• How are we able to later view if account migration is still in progress? If I see proccesses like
  Code:

  /bin/gtar -x --no-same-owner -p -f - --no-wildcards-match-slash

  or
  Code:

  /bin/cat /home/cpmove-username/homedir.tar

  denote a migration in progress?
• Should I wait until no more procceses like those appear to resume the account migration?
