Hi Vaan,
The bc-chshen03 and bc-chshen04 are on now.
I have reverted BCS12-Lync-01.core2.sqm.testnet.rim.net and BCS12-ST-01.bbapps.sqm.testnet.rim.net back to baseline
Please install 3.10.1 Columbia build if SV&V sanity pass. And go over the 8 steps in my original email.
Linda has started trying to install, from her email conversation with development team, I see there are quite a few things we need to figure out from dev, so we will start the installer test after the new year when we all back to office
