Hello, im currently tasked with migrating a Jira 8.2.3 to a newer version 8.12+, since we are moving to aws and are using a mysql 8 on it.The problem here is that the MySQL used is 5.5.28, so massively outdated. Im currently testing this on a step by step basis as follows.With a copy of the production:Upgrading MySQL to 5.5.53 (latest 5.5 mac supported version)Upgrading MySQL to 5.6Upgrading MySQL to 5.7Upgrading Jira to 8.12Upgrading MySQL to 8.0Is there anything i need to additionally keep in mind? or an easier soloution?I have been going through various guides and documentations. i.E:https://dev.mysql.com/doc/refman/5.6/en/upgrading.html What i managed to Identify so far is that i need to switch from utf8 to utf8mb4.Are there any changes beetween mysql 5.5 and 8.0 that affect jira?
