Blog in 3.9. Edit later in 5.x

Hi Support

This one is easy and does not involve jumping through an IP hoops

Can I write a post in EB 3.9
And re edit it later in EB 5.

Specifically I want to add videos in EB 3.9
And then put them in the EB 5 video template at a later date.

i.e. re edit a blog post using EB 5 later....

thanks in advance

Paul
