Need Help Transfering custom database to latest data update

Hi Guys, new to making custom databases, I have re-unified the Republic and Northern Ireland (touchy subject I know) at both club and international level first on default 20.1.0 database, and want to update it all on 20.4.0 but as I have made 1691 database changes I really really do not want to go through them one by one again, I am a novice at messing with the editor so I am just wondering is there anyway of transferring all my changes over to a 20.4.0 file all at once or is this not possible? thanks in advance

Generally speaking, changes should be transferable between databases. So you should be able to use them even in 20.4. Load it with that database and check if everything works as it should

open file select details it will show DB changes and if there any failed changes

run a search for the failed changes in the categories you have edited if there are any you can try to re edit any failed changes then
NB save the file in the 20.4 DB then (but either copy the original file, or rename it 20.4 etc and use ''save editor data as '' this way you have the original file as a back up)
