Did you reinstate the doors? because we found that cards were being denied after the upgrade stating "Access level not valid" and reinstating the doors fixed it.

Powercycling the ACU's doesnt delete any config off it. I suspect if the nodes are ticked on in the config utility and you give each ACU a powercycle they will come back with a green tick (they will show a server connected light above the link light on the ACU). Once they do come back they will update to the latest firmware, and then you will probably need to re-instate them to pull down the card data.

Try 318 doors! we also had issues moving servers and I suspect one of the doors stopped the rest updating... and because we have several VLANs powercycling the ACU's wasn't enough... we had to do a TCP/IP reset on most of them!! took three days to fix them all.
