Last week the SharePoint Team Blog had an article on planning for upgrade to SharePoint 2010. Whilst there’s nothing surprising in the article, there are some useful links to download latest service packs. The key point is that in order to run an upgrade then you must be running WSS 3.0 SP2 or MOSS 2007 SP2.
If you’re not already on SP2 it makes sense to include any SP2 install in your planning exercise for the upgrade. It also notes that there is no direct path to upgrade from WSS 2.0 or SPS 2003 (of course!) and so these first have to be upgraded to WSS 2.0 or MOSS 2007 [although trial versions of the software are supported in the upgrade and migration process, so no new licences required].
The key points surrounding an upgrade to 2010 that I’ve seen so far then are:
- There is no supported upgrade path from SP2010 Beta to RTM
- WSS 3.0 SP2 or MOSS 2007 SP2 are required
- 64bit architecture is required
- Visual upgrade path available – allowing users to choose when to convert their site to the new UI
There is also the stsadm pre-upgrade check tool that is included in SP2 which very quickly provides an audit of the servers in a SharePoint farm to see if the core requirements for upgrading are met.
