Maintaining Notes clients

Upgrading Notes to the latest maintenance release and Fix Pack is a better choice than applying hotfixes

Follow the below steps to avoid hotfixes:

Maintenance releases and fix packs are maintenance deliverables for Notes and Domino that are planned, scheduled, well-tested, and manageable.
Hotfixes have the following disadvantages:
- Limited customer eligibility.
- Intended for only the most critical issues.
- Extensive testing by customers in their environments is required as they are minimally tested by HCL.

For information about the fixes provided in each release and Fix Pack, see the Fix List.
