Hello,
WoodMart doesn’t have a built-in import or migration tool for the WooCommerce Waitlist plugin, or for any other waitlist plugin. The two plugins store their data in different ways, so subscribers can’t be moved over automatically.
You could still move them with a custom script. The WoodMart waitlist must be enabled first in Theme Settings -> Shop -> Waitlist. The database table is created only after you turn this option on.
Please note that writing a migration script counts as custom development, which our support doesn’t cover. We’d also recommend making a full database backup before running any import.
Best Regards
