In short words SP2 based on the Feb CU but not contains April CU fixes.

We highly recommend to install SP2. In case you need April CU please also install SP2 first.

Suggested steps to upgrade:

• Have a test environment similar to your productive.
• Create a complete backup for all SharePoint data and a system backup of all WFE’s.
• Install SP2.
• Test briefly the functionality.
• Install April CU.
• Test the functionality as deep as possible.
• With that experience do same steps in the production environment.

April CU KB articles

For WSS we can offer an uber package with the KB number 968850. This package contains the two KB 968857 (Global) and KB 969421 (Language specific) hotfix packages.

The KB articles are not yet finished and I will post the URL’s when these are available.

For MOSS we cannot offer the uber package yet because of a similar problem we had with Feb CU.

What to install now?
- SP2 in any case
- WSS April CU uber package on WSS only environments

- You had a hotfix request with us and needs a MOSS fix? The escalation engineer will update you which package is the right one.

Later when the uber package for MOSS will be available we also recommend to install WSS and MOSS uber after SP2 on all SharePoint environments.
