The other day I attempted to replace a buggy PLM with a new device. Per the WIKI manual, I unplugged the 994, then connected the new PLM, then repowered the 994, then selected "restore PLM" in the admin console. The "system busy" box then displayed but progress stopped at ~25% (4 tries). l then tried "restore devices" but got nowhere. I ended up reinstalling a backup ISY file to restore the system back to where it was (I had deleted a number of unused nodes in an attempt to streamline the PLM search process). 

Any suggestions/comments on what the problem is? 

As you can tell, I'm a rookie at this. 

Do you have battery devices like motion or door sensors? Those have to be individually put in set mode for their turn. There's a little battery icon with a +/-on the top of the admin console you can click. It will avoid all battery devices so powerline devices finish. Then you unclick it and do each battery device one at a time

Good question. I noted this while reading the WIKI info. I have several battery operated devices (i.e., water sensors in the crawl space). I planned to address these after I installed the new PLM. I will look at the admin console for battery icon. Do you believe that this was the cause of the failure to update?

It's possible. I believe the admin console steps through the list of devices and won't avoid sensors unless that battery option is set.

It's easy to try and see if it will complete.

Thx. I'll try again

Hard to say for sure, but relatively easy to eliminate as the culprit.
