I am in charge of upgrading a JIRA instance from 3.13.5 to 5.2.10.
I intend to do a manual upgrade with Oracle 11 database.
The target process is to upgrade straight from 3.13.5 to 4.4.5 and finally to 5..2.10.
Do we need to apply some manual Oracle scripts like described here ? :
Or eventually, are these scripts already included in JIRA Upgrade Tasks when the application starts the first time?
Thanks for you help.
Depends on how you are doing 3.13 to 4.4.
If you're exporting the XML and then importing it, then no, 4.4 will create the correct database layout and import the data.
If you are pointing the new 4.4 at the existing 3.13 database and expecting it to do all the work, then yes, you need to follow those instructions - shut down 3.13, take a backup of the database, run the scripts and alterations, start Jira 4.4
Two pretty obvious points here, but I've seen people skip them and create nightmares. 1) Test it properly on non-production systems before you start and 2) Backups. Database backups are your friend. Be nice to them...
It is only because there are column format changes between 3.x and 4.x and the code in Jira doesn't cope with those changes. Fortunately they are actually reasonably simple (heck, I can follow the script, and my DBA knowledge is little more than "select from where"). A clean install followed by import of xml bypasses the problem because it creates the columns in the right format, but that's not always the right answer for every situation.
Fortunately, you'll find 4.x to 5.x has nothing anywhere near as scary in it :-)
