Moving Content from one Ruleset to Another Ruleset?

Hi. Is there an easy way to move content from one ruleset to another?

Here's my exact scenario: I've been playing an using FG for a long time, and have content from way back in the day, that I'd like to use in my current campaign. More specifically, I have content from my old 3.x campaigns that I'd like to use in my current PF2e campaign - primarily the story entries and maps. Right now, all I can figure is either importing the original media into the new campaign (if I still have it), or copy-n-paste between the two. Otherwise, I'm stuck re-creating the old content in the new campaign. Is there a better way?

On a similar note, I've also purchased a number of adventures for other systems/older editions, and have the official FG versions, as well as PDFs. Again, I can reenter the content, etc. But is there anyway to transfer the content? For example, if I want to use the old B3 module (of BECMI/1e fame) in my current PF2e campaign is there a way to easily transfer/import that content?

Take a look at the Universal Extension. It should work with maps and story entries. It's on the forge here:

This would allow you to open the old modules and drag the maps and story enties to duplicate them in your new ruleset of choice.

As Griorge says above you can use the Universal modules extension to get the data into a campaign using a different ruleset. You'll want to create the modules first from your original campaign; see here https://fantasygroundsunity.atlassia...#Module-Export

Once you create the module of your old campaign and open it in your new campaign, you can copy the items if you don't want to have to have th module open.

But, I would consider taking the time now to organize. You might have many hundreds of stories and images from your old campaign and that can quickly become burdemsome. Though its significant work, you could take the time to break the old content up into multiple modules that you and, if desired ,the players, can load and unload as needed.
