Many have asked me, did Zimbra Collaboration (ZCS) 8.6.0 Patch4 will include Patch1 to Patch3? Actually, if you read the release notes document, the answer is there. ZCS patches are cumulative, meaning ZCS 8.6.0 Patch4 includes ZCS 8.6.0 Patch3, ZCS 8.6.0 Patch2 and ZCS 8.6.0 Patch1. These patch release notes provide information about the Zimbra Collaboration (ZCS) 8.6.0 Patch4, including the enhancements, bug fixes, security fixes, considerations, Known issues, preparation before installing the Patch, step to install the patch, example of the Patch script and revision history information. This step to install zimbra patch has been tested on RHEL6, CentOS6, Oracle Linux 6, RHEL7, CentOS7 and Oracle Linux 7.
In release notes document (preparation before patch), one of the steps we need to take into consideration is to perform a full backup before applied any patch. This is because there is no automatic roll-back if anything goes wrong. If your environment is currently using VMware Vsphere, you can do a virtual machine snapshot before start installing any patch.
