Merge 2 similar DB

Hi ,

From the beginning, I've had one DB on a private server and a similarly links structure and fields other DB on Ninox server. I've upgraded them simultaneously, but I may have forgot some, so they are 95% similar.

Now, I'd like to merge these 2 DB into one.

First, how to do that?!

Second, isn't there a risk of great mess if Tables or formulas aren'r exactly the same in the 2 DB ? Which structure will prevail? Is it possible to fix when merging or later ?

Looking forward to hear your adwise, and being at your disposal,

Regards,
