applications. In some cases, you may need to upgrade to a later version of a third-party

application

to support Domino 8. Understanding the version and patch requirements for your third-party applications is

critical to your successful deployment.

Deployment Sequence

When planning the upgrade to Domino 8.5, one of the first and most important considerations is which

components of the Domino infrastructure to upgrade first and are there any key dependencies in the

upgrade process?

We recommend the following upgrade sequence:

• The very first step is to upgrade all tools which are used in more than one domain (for example,

User or Database Management Tools). Make sure that all these tools are still working with your

previous versions of Domino after upgrading as you will have a mixed environment for some time.

After that you can start to upgrade your environment on a per domain basis.

•

The next step is then to upgrade the domain’s administration infrastructure, which means:

• Upgrade all administrator clients to R8.5

• Upgrade the domain’s Domino management infrastructure

• Upgrade the Domino directory and the administration request database of the domain. How to

upgrade them is described in a later chapter of this document

• Upgrade all Domino infrastructure servers in the domain

• Administration server of the directory (this needs to be the first server)

• Any hub server and other directory servers.

• SMTP- and other gateway servers

• Upgrade all spoke servers

• Upgrade all mail servers

• Upgrade all application servers

• All end user Notes clients

Finally, complete the upgrade process by

•

Upgrading the design of your mail databases and any new application functionality.

At this stage, you can really start to take the full advantage of your upgraded Domino infrastructure,

especially from an application point of view.
