Hi, We have a really old version of jira (7.3) which is in our data centre. We are looking to upgrade both jira (to 8.13) and the app/ database servers.
Now, can someone suggest the best approach to do this please? its a non-standard product so a lot of add ons etc. I see below two options :
1) We do a fresh install of 8.13 on new app server and point it to 7.3 database. Not sure if installer will upgrade the database while doing this.
2) We install 7.3 on new app server first and then upgrade it to 8.13. We might run into windows compatibility issues etc while doing this.
Any guidance is much appreciated.
Many Thanks.
