Will the DIVI theme crash if I upload a site database file made before the DIVI update?

Question

WordPress

Updated DIVI so that you can correctly transfer the page from another site (there was already a fresh version there).
Some styles are off.
If I drop the database file that I made through backup before updating divi, will my theme completely crash or will it be possible to fix the crashed styles?

Maybe you can add a file with css (there styles were written manually) from the backup to add to the current one?

Moreover, if you go into the divi page builder itself, then everything is fine with the page
