RE: [WIRELESS-LAN] WCS 4.2
What specific issues have people seen with upgrading WCS to 4.2? One of our admins is trying to do the upgrade right now, and the install seems to be getting stuck at the sql upgrade script.

There is always downtime with an upgrade. Also, they upped the limit in the 4.0.206 to 10 APs at a time. -Original Message- Also the 4.2.62 has new code for the access points, so each will need to download the new code. Remember this takes about 4 minutes per access point and each WLC can only upgrade 4 at a time, so 8 per WiSM.

RE: [WIRELESS-LAN] WCS 4.2
Our one-touch installer stalled during the .exe- said it saw multiple copies of WCS, but only one anywhere is what we were upgrading from. Searched the server far and wide for traces of any earlier versions, and all earlier upgrades went fine (except one that I'd rather not relive). I upgraded manually and all was well, except for many of the bugs that I hoped would be fixed our still present. Lee H.

I would be interested in any feedback on the upgrades to WCS 4.2 as well. Any gotchas or heads up would be appreciated. Lee - Could you please describe for me the One Touch Process you mention?

From what we were told by Cisco - you will no longer have to remove the old and then install the new. All version from 4.2 on will be a single install and will remove the old for you. todd Todd Joyce Network Services Radford University - The Smart Choice [EMAIL PROTECTED] (540) 831- Keep your boots and ChapStick and ice hotels.

If you have configuration issues after upgrading to 4.2.62 - DON'T - try to load a backup config file from 4.xxx code to the new 4.2.62 WLCs. I made this error and put 5 - WLCs (2.5 WiSMs) back to the install wizard. We had to manually console into the WiSMs and start from new. We ran into this on a 4404. The solution was to connect to the console, clear the config NVRAM and then boot the 4.1 backup image. Once on the backup image, do enough of the configuration script to get the WLC on the network and D/L your saved 4.1 config. Then, save the config to flash and restart the controller on the main 4.2 image. The boot process will do the config upgrade for you. The release notes say they switched from a binary file to an XML based file format. I'd have thought the config process would be a little more robust and able to handle both versions.. Guess not. -JEff ** Participation and subscription information for this EDUCAUSE Constituent Group discussion list can be found at http://www.educause.edu/groups/.
Re: [WIRELESS-LAN] WCS 4.2
Doug, Thanks for the posting. I thought that each WLC on a WiSM can download 10 APs at a time. In 4.1.185.0 code we typically see 9 APs being download at a time when doing a bulk AP upgrade to LWAPP. On our 1230 APs the download seems to take approx 1.5 to 2 minutes. It sounds like you are seeing very different results in 4.2? We haven't deployed v4.2 into any production sites yet. Would you care to share any gotcha's with v4.2 in production that you have seen? Thanks, -Charles Charles E.
