If only this was the case. Sadly not 
Ok, just upgraded from P23 to P26 and wanted to share my results. It went pretty smoothly just a few hiccups. After adding new Homey to account from backup none of my devices worked. I read that in a post that you just do another reset and restore from backup again. Before trying that I just did a reboot of H26. This actually made all but my zwave devices working . . sigh of relief. Now for the zwave I was receiving a node error and since I only have 4 of them I decided to remove and re-add them instead of trying the reset method. Now just need to fix the flows that were associated to the old zwave devices and add the new device flow card in its place. Keep in mind I just did the change yesterday, so limited testing of flows, but all devices work. All in all it was a successful upgrade as far as Iām concerned. 
What about zigbee devices?
after reboot of hub they all are working.
You are a very very lucky man. If you read the posts, lots of others not so lucky.
