Just wanted to let you know - today is the day two updates will be available to you to assist in your management and deployment of WSUS 3.0.
First ,we are making an update available for WSUS 2.0 SP1, which will create a 3.0 "self update tree" on your WSUS 2.0 /SP1 servers. The self-update tree update contains the code for the WSUS 3.0 client. That means, once this update is approved and installed on your WSUS 2.0 SP1 server, 2.0 clients "mapped" to that server will be "self updated" to the 3.0 client the next time the client 'checks in' with the WSUS 2.0 SP1 server. The server remains WSUS 2.0 SP1, while the clients are able to update themselves from the server, to the 3.0 version. We did this to ensure customers had a distributable method to update their clients and realize new performance optimizations, but still manage the plan and timing to upgrade the servers to WSUS 3.0. This update is classified as a critical update for all server categories on which WSUS 2.0 SP1 is supported, with the exception of SBS R2.
Additionally, WSUS 3.0 will available via WSUS today, classified as an "update" and targeted at Windows 2003 SP1 for WSUS 2.0, WSUS 2.0 SP1 products. There will be 2 updates since 3.0 now natively supports x64bit. They are:
Windows Server Update Services 3.0 (KB935524)
Windows Server Update Services 3.0 for x64-based Systems (KB935524)
Again, this update will be classified as an “update” targeted at Windows 2003 SP1 for WSUS 2.0 and WSUS 2.0 SP1. Also the update will be used to upgrade WSUS 3.0 RC to RTM on the Windows 2003 server.
Hope this helps and happy updating!
