Migration happens in the same way from WAX on EOS as from EOS on WAX.
- enter your in-game Account Tab in the right upper corner of the window
- choose the 'Migration' Tab
- enter the amount of PGL you want to migrate
- choose the chain on which you would like to migrate them, specify an account name
- confirm the action
Migrated PGL will appear on the selected account 2–4 min later.
