I recently read the things to know when upgrading Unity from a TAC newsletter. The article stated that 2.1 and 2.2 customers would need a new dongle. It also had a list of the supported upgrade versions. The list does not include the version 2.3 build I am about to run an upgrade on a Unity with unified messaging that is at the build and would like to know if I can upgrade with only the software and nothing else. I have already posted the question in the past and the response has been that I can just upgrade but this new tech note without the build listed that I am currently at concerned me. Can I get a definitive answer? Thanks in advance. <br><br>

Re: Upgrades

2.3.4 build 104 is the oldest version QA tests with when doing upgrade test plans. The differences between build 102 and 104 are minor and shouldn't cause you problems BUT I have to say we don't test with that version so there is an element of risk involved here.

That's the best answer I can give you. Be sure to backup your system before upgrading (which is always a good move regardles).
