Openfire upgrade

I’m currently running openfire 3.4.5. on windows.would to upgrade to 3.6.4. and would like to know if anyone has experience with this upgrade. I have more then 100 users and I don’t want to screw up anything.

main reason for this upgrade is that one of my senior manager would like to see chat history and according to what I have found is that my current version is not capable of doing this.

Any help will be appreciated.

I suggest to make a backup of you current installation and of your database and then try upgrading, if something going wrong then just revert to your backup and post here about the problems.
