ZCS 5.0GA NE Has Been Released!

[jholder]

The Zimbra Team is very happy to announce Zimbra Open Source 5.0 Network EditionGA is now available.

Please be sure to read this announcement in full.

With about 5,000 bug fixes, and enhancements logged to our bugzilla, Zimbra 5.0 is by far the most feature packed and advanced version we've ever released.

As we release this version, please note that there are known issues, that are not resolved in this upgrade. They will be fixed in a future maintenance release. You should review these issues prior to your upgrade. If you would rather wait, we will be providing an update early next year.

Zimbra strongly suggests that all users perform a full backup of their existing system prior to running the upgrade script.

The upgrade time can vary greatly depending on how many users you have. You should plan accordingly.

If upgrading, please keep in mind that any customizations that you've done, such as altering configuration files, may not be migrated. You should back those files up.

Additionally, there are several component changes within Zimbra. If you are using Zimbra components (such as ldap or SOAP) in other services, please be sure to backup your configuration.

The upgrade script will remove any zimlets that are not compatible with Zimbra 5.0. Skins from 4.5 also may not work under 5.0.
