Upgrading one R7x Multi-Domain Server with Gradual Migration of Domain Management Servers

Attention:

This upgrade method is supported only when you upgrade from R7x versions.

We recommend to upgrade the entire Multi-Domain Server at once with one of these methods:

Because upgrade of the entire Multi-Domain Server at once is the default recommended method, use the Gradual Migration of Domain Management Servers only in these cases:

  • The entire Multi-Domain Server cannot be upgraded at once because of a business impact.

  • During the upgrade, it is necessary to rename some or all of the Domain Management Servers.

  • In Multi-Domain Server High Availability deployment, it is necessary to change the number of Domain Management Servers on Multi-Domain Servers.

If you use the Gradual Migration method:

  • You must migrate the Global Policies before you migrate the databases from other Domains.

  • You can migrate the Global Policies only one time from the R7x Multi-Domain Server.

  • Until the entire migration procedure is completed, you cannot make changes in the Global Policies on the source Multi-Domain Servers.

    If it is necessary to make changes on the source Multi-Domain Servers, follow these guidelines:

    • If you deleted or modified a global object in the source R7x Multi-Domain Server database, you must make the same changes in the migrated Global Policies on the target R80.40 Multi-Domain Server.

    • If you added a global object in the source R7x Multi-Domain Server database, you must delete that global object before you export the databases from other Domains.
