Is there a way to move the index to a new location without migrating or updating database tables? We want to test out faster SSD's but only want to move the index not the whole partition that JIRA is installed on. It looks like you used to be able to set a custon index location back in 4.1
What operation system do you use? if that is linux - move caches folder that is inside jira home directory to the new place and place symlink on it. Well, for windows the same)
We run Windows server 2008 R2. If we used symlinks would we actually see an increase in performance moving to SSD's? If its just a shortcut to the slower folder/drives? Maybe I'm confused how symlinks work and I'm surprised Atlassian doesn't have a recommended solution for moving indexes. Thanks for the responses!
you have 2 drives, drive C (slow), drive D (fast)
On drive C you have installed jira with jira data folder in c:\jiradata
Indexes are located at c:\jiradata\caches
You move that caches folder from c:\jiradata\caches to d:\caches and create a symlink at drive C inside c:\jiradata folder that will point to d:\caches
Now every time jira tries to open file at c:\jiradata\caches\... it is automaticaly non-transporently redirrected to drive d:\caches and file is actually opened from the new fast drive. So you actually execute read-write operations with that new drive.
1. You MUST have Jira offline when you do this move and link, or you could partly trash your index
2. Shortcuts will NOT hack it, the drive MUST be mounted and linked into the right place. (Users of superior file systems have access to easy symbolic links, soft and hard, and can even mount drives in the right place, it's an absolute doddle. But if you're stuck with Windows, you'll have to use the less-than-ideal way that MS have implemented "symbolic links" 20 years later than everyone else). I'd strongly recommend the use of "mklink" on the command line, rather than using the GUI - I've had problems with symbolic links disappearing and users creating shortcuts instead of links when they use the GUI. mklink forces the issue.
3. Copying the index files like this almost always works fine. But if you do get errors, then a full re-index will fix it fine. You could even skip the copy - just create the links, restart Jira and re-index

Please also note that hardlink can exist only inside the same volume, please see http://msdn.microsoft.com/en-us/library/windows/desktop/aa365006(v=vs.85).aspx
You need a symlink for directory or junction(soft directory link)
