When planning to upgrade your existing Domino infrastructure, it is important to understand what is needed to get your environment ready to accept Domino 8.5.
Understanding prerequisites
Preparing for an upgrade includes understanding and meeting all prerequisites for the upgrade, all the things that need to be in place before you begin the upgrade. Things to consider at this stage include:
- Does your operating system meet the minimum requirements?
- Does your hardware meet the minimum requirements?
- Do you need to upgrade existing server hardware?
- Do you need to add or replace server hardware?
- Do you need to add more network bandwidth?
- Do you need to add more storage capacity?
- Does it make sense to consolidate?
The information that you have gathered in the infrastructure assessment should be used to help determine what actions will be required to meet the prerequisites to deploy Notes and Domino 8.5.
Evaluating server readiness
The tables below compare system requirements from Domino 8 to Domino 8.5 for all supported platforms, to allow you to determine if your hardware needs to be upgraded or replaced. The Domino 8.5 requirements are based on system requirements for Domino 8.0.2, as listed in the release notes for Notes and Domino 8.0.2.
Detailed system requirements for Domino 8.5.1 can be found in IBM Technote 7016204 http://www-01.ibm.com/support/docview.wss?rs=463&uid=swg27016204.
Note that with Domino 8.0.2, additional platform support was added to enable you to prepare your systems for Domino 8 prior to its release. This allows you to bridge any gaps you find in your preparedness now, in advance of deploying 8.5, and removes the need to perform hardware, operating system, and Domino upgrades all at once, allowing you to segment your upgrade activities in the most appropriate manner for your environment.
A comprehensive list of requirements is provided with IBM Technote 7007909 http://www-01.ibm.com/support/docview.wss?rs=463&uid=swg27007909.

Features
When upgrading or deploying Domino 8.5 it should be part of of the rollout plan to define the new features you’re going to activate.
Sizing
For a checklist to use when sizing a new Domino server, see Techpaper 7008851, "Notes/Domino Best Practices: Sizing", available at this URL: http://www.ibm.com/support/docview.wss?rs=203&uid=swg27008851
If you are planning to run your Domino server inside a virtual machine, please read technote "How to size Domino and Sametime systems for full production loads on VMware ESX Server"
http://www-01.ibm.com/support/docview.wss?uid=swg21267837
Consolidation
When reviewing your Domino environment, you may have found your environment in need of some level of consolidation, such as domain consolidation or server consolidation. If you are considering consolidation, it would be wise to conduct the consolidation as part of your prerequisite activities. While consolidation is not a prerequisite, best practices suggest that, should you want to consolidate, you should do so before upgrading, to avoid making multiple changes at once. Then upgrade those servers to Domino 8.5 only after the consolidation has been successful.
For more information about consolidation, see "Domino 7 Server Consolidation: Best Practices to Get the Most Out of Your Domino Infrastructure", REDP-4181, available at the following URL:
http://www.redbooks.com/Redbooks.nsf/RedbookAbstracts/redp4181.html
Compatibility
Although Domino itself is backwards compatible, there are some things to consider when upgrading an existing environment.
Application considerations
From an application perspective, there a few things to consider when planning to upgrade your application servers. While it is not necessary to rewrite your pre-existing applications, we strongly recommend testing your applications on Domino 8 before upgrading your production application servers.
In previous steps, you collected the information about your applications. Using this information, you can target your testing appropriately. Additionally, once your application has been tested and the application server upgraded, you can consider modifying the application to take advantage of new application development functionality in Domino 8.5.
At this stage, you may want to identify the new application development features you would like to leverage in your Domino applications. For more information about this, see the
Application Development pages in this wiki.
Third party applications
Your third-party applications also have prerequisites, and server readiness includes making sure that your environment meets the prerequisites for supported versions of your third-party 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.
