how can we migrate wordpress 5.9 website from aws ec2 to new installed wp 5.9 oci compute

I have websites that contain some free@minimum and paid editors of WordPress (eg.elementor which supports only single sites' license) now wp 5.9 has come out with full site editing features.it is instructed to migrate the website from the existing website to the new version. only regular methods of upgradations won't able to facilitate the full site editing. and also I need to change the MySQL character set during the migration process. I can understand if we can just copy the content folder from the source to the new target instance if it is a blank WordPress site or we may use some cross-domain plugins to achieve so but I have a paid plugins to deal with ie. the major concerns for me.

can anyone share the plan of action for this simplest task with some hints? we would do it from domain to domain import/export without any issue if there wouldn't be any pro plugin but what will be the best approach now. I am looking for some clue.

thx
