Will this release be a v1 production ready release or another preview?
Hi Matt, this release is a preview release.
Hello Han, As per your notes Step No.( 3 ) Click Upgrade Agent on your Client Agent window. But my agent Upgrade button is dis-active / disable I can not click on it. (For your information my Agent version is 18.104.22.168) So please reply me asap. I do not want to recreate sync group.
Because my sync groups earlier created all agents version is 22.214.171.124 currently I can sync but if I can not upgrade all agent on after which date I can not sync please reply me date and time zone.
I have the same issue. My version is 126.96.36.199 and I see the latest version for download is 188.8.131.52 (published 6/6/2012). I am confused! Do I upgrade or not?
The upgrade button will be enabled after old agent (version equal and lower than 184.108.40.206) reach expire date (Jun 08 23:59:59 UTC time).
So you shall be able to click the upgrade button now
or you can go to www.microsoft.com/.../details.aspx directly and download the new agent (version 220.127.116.11).
