The Zimbra team is pleased to announce the availability of Zimbra Collaboration Suite 5.0 RC2 for the Network Edition and Open Source Edition.
RC2 marks another big step in our progress towards Zimbra 5.0 with 767 more bug fixes and enhancements than RC1.
This is the first beta of the Network Edition. This is BETA quality software and Trial users may get Support from Zimbra support. Open Source users, please use the forums. It is not possible to upgrade a current Network Edition install to RC2. Do not run RC2 in a production environment. We provide it for testing ONLY.
RC2 Network Edition connectors, such as ZCO and iSync, should only be used against a RC2 Server. Using these tools against a 4.5 server may have unintended consequences.
We cannot stress enough the importance of keeping current backups. Users should backup before the upgrade, and keep backing up after the upgrade to avoid any possibility of data loss.
More information on backing up can be found here: Backup and Restore Articles - Zimbra :: Wiki
If you believe you have found a bug, please file it in the Zimbra Bugzilla.
We hope you enjoy this preview of the Next Generation of Zimbra Collaboration Suite:
