Integration with Webinar Press plugin: Help needed

Hello
I have purchased pro version of this plugin from code canyon and i have purchased https://codecanyon.net/item/wordpress-multisite-posts-pages-and-custom-post-types-sync/20143748?s_rank=5 and https://codecanyon.net/item/woocommerce-multisite-content-copier/19660524?s_rank=8 and i need help with migrating webinar press webinars from one site to another in WP Multi site.

Here are issues that i am facing right now:
I am migrating webinars from SiteA to SiteB:
1- When i migrate Webinars and products from SiteA to SiteB: Both webinars and products have a relationship in between based on their post IDs . But when the Posts are migrated from SiteA to SiteB, their relation ship gets broken as post IDs are getting changed.
Can you please confirm, how can i migrate these.

I can do customization as well. Is there any hook or action reference for this plugin? which action/hook is fired when a post is migrated.

Waiting for reply

Sajid
