simonsez Posted July 11, 2013 Posted July 11, 2013 I just purchased an ISY994i to replace my existing ISY99i. I have read the instructions (http://wiki.universal-devices.com/index ... r_ISY-994i) in the wiki about upgrading and it seems simple enough. My ISY99 is v3.2.6 and the version on the ISY994i is v4.0.5. I was wondering if there would be any issues upgrading from the old version to the new version? I did try upgrading the ISY99 a while ago to a later version, but I had a lot of problems after I did so I went back to the old version since I was planning on buying the 994 anyways. Other than that, if there are any other tips or tricks I'd love to hear them. I'm just waiting to have my modules transferred and then I am planning on doing the upgrade. Thanks. Simon
jtara92101 Posted July 11, 2013 Posted July 11, 2013 I just did this, and there are a couple of posts here about my experience. You need to make sure your isy99 is updated to 3.3.10 first. Save a backup, then on the isy994, restore from that backup. You don't need to downgrade to 3.3.1.0. 4.0.5 (on the isy994) can read the 3.3.10 backup files. Make sure you unplug your PLM from the power before connecting it to the isy994. Otherwise, it will think it is still talking to the isy99.
simonsez Posted July 12, 2013 Author Posted July 12, 2013 Hi jtara92101, Thanks for your tip. I searched the forums for your messages and gave the relevant threads a good read. Feeling confident I went ahead and did the upgrade to the 994. So far it seems like everything is working, but I need to do a bit more testing to be 100% sure. At any rate thanks for replying, it was really helpful. Simon
