There is currently not a built-in functionality that will merge data/resources between multiple HubSpot accounts.
There are, however, certain steps you can take to move assets from one HubSpot account to another. Take a look at these steps below:
- You can export contacts from one account and import contacts into another account.
- You can use the Copy template feature to move templates from one HubSpot account to another.
- You can export your website pages and then manually add them to another account.
