Upgrading Multiple Sites Running Different Versions
A Zerto Virtual Manager can be installed on a site running a different version, as long as each version is only one version higher or lower than the other.
When you have multiple sites, make sure that the version of Zerto Virtual Manager is never more than one version higher or lower than any of the versions running on the paired sites.
To upgrade Zerto installed on multiple sites:
|
1.
|
Upgrade a site whose version is lower than the required version. Start the upgrades with the site whose version is lowest. |
Make sure, at all times, that no site is more or less than one version higher or lower than any of the paired sites.
|
2.
|
If the VRAs on the site need upgrading, upgrade these VRAs to ensure that they are no less than one version higher or lower than any of the VRAs on any of the paired sites. |
|
3.
|
Repeat the above step for all sites. |
For Example:
|
•
|
You have sites running versions 5.0U3, which are paired to a site running 5.5U4. |
|
•
|
You are planning to upgrade to 6.0U2. |
|
•
|
Upgrade first the 5.0U3 site to a 5.5U4 version, and then both of the sites to 6.0U2. |
