Multi site migration Pro

Hello,
We are doing a migration of site from a multi site to an new multi site. Is there an issue with page builder plug ins? We have installed(migrated) a site that had pages built with Elementor, We can not edit these pages. Wondering if there is a sequence that needs attention before migrating a site with said plugins. Or a fix? Our thought is to upload the plugins BEFORE the migration, but would like to know if that truly makes a difference. Any help would be appreciated. Thank yo in advance.
