Hi Team ,
The story is , Currently we are using JIRA 6.2 version (with MySQL database), and we want to get new version 7.3.0 in a totally new "Production Application Server" with a new database "MSSQL 20.12". and .
So please do tell us best Approach.
And also please clear our doupt whether we can directly install JIRA 7.3.0 with the older MySQL database copied over to MSSQL database?
Do we need to first install 7.0.0 then move to 7.3.0 in the totally new enviroment.
I don't have any experience with neither myself but I did find some information online.
I would start by migrating your current environment to the new database technology. There are guides available on Confluence that should help you: https://confluence.atlassian.com/adminjiraserver071/switching-databases-802592192.html
After you've done that you should upgrade to 7.0.x first after which you can upgrade to 7.3.x. All the details and steps to take for your setup can be found here: https://confluence.atlassian.com/migration/jira-7?tab:product=1&tab:platform=1
No, 6.2 to 7.3 is not going to work, it's too large a jump around a major upgrade.
There are three upgrade routes I might look at
If your installation is simple and has few or no add-ons, there is a good change route 1 will work. If testing that shows any problem at all, I would not bother trying to fix them, as it won't be worth it. It will be easier to take your 6.2 to 6.4.
After you're on 6.4, there is a good chance going to 7.3 will work fine. If that does have any problems, then you'll need to fall back to the officially recommended route, which is line 3.
