You should always read the upgrade instructions, and you absolutely must read the release notes for each version you're going through (not the point releases, but you really should read the notes for 5.0, 5.1, 6.0, 6.1 and 6.2)

is it mandeoty to have both instances of same version to migrate?

Sorry, that's nonsense. You're trying to upgrade - now you've said you want to upgrade to the same version? Which isn't an upgrade? Eh?

I meant, currently i have 2 jiras

one is latest 6.2 and another is 4.4.4 and i want to migrate 4.4.4 to 6.2

My question is - Shall I upgrade it and then migrate or directly migrate to 6.2

I guess i have to first upgrage to the version where i want to migrate

please let me know your thougts?

when i crate new 4.4.4 system , is it ok if i change database type e.g. MSSQL to MYSQL

Ohh, I see, sorry.

It's slightly different use of English than I'm used to. Migrate to me means "move from one place to another", and I'd use "upgrade" for changing the versions, and "merge" for taking stuff from one instance and putting it into another one.

You are right about the merge of Jira installations - if you're going to use the built-in project import, they need to be the same version.

In your case, I would

  • Create a new 4.4.4 system, from the 4.4.4 data
  • Upgrade it to 6.2 as a test
  • Migrate to it later when you've passed testing
  • Then you'll be able to export from the 4.4.4/6.2 system and merge it into the existing 6.2

Yes. But I'd treat it as a distinct separate step. If you were just copying the existing 4.4.4 data, you can just grab a copy of the database and restore it into a new area.

To change the database, you'll need to configure the target Jira to use it, and then the easiest route would be to export your 4.4.4 data to xml and import it into the empty mysql-backed Jira.

I always recommend to install another instance, and import your data to the new instance, so you will have a most recent version and also will keep the previous one as a backup in case something goes wrong:

These are my recommended steps for upgrade:

  • Backup your current database.
  • Create a new and clean database that will be used for the new instance.
  • Install the new instance using the new database.
  • Install all the plugins present in your old instance.
  • Log in to the old instance and export a XML Backup.
  • Log in to the new instance and import the XML Backup.
  • Copy these folders from the older JIRA_HOME to the new one:
    • <tt>$JIRA_HOME/data/attachments.</tt>
    • <tt>$JIRA_HOME/data/avatars.</tt>

the reason behind upgdare is to move it to latest existing another version of jira which we are planning to use acroos departments.

what is your thought. Shall i upgrade as you said then migrate or directy migrate it to latest existing version
