A few days ago, Service Pack 1 for UAG has been released, but we have seen some confusion with customers with regards to the type of updates UAG may have and how they relate to each other.
UAG can have the following types of updates:
1. A private fix, which the product-group may issue to resolve a specific issue that has been discovered.
2. A hot-fix, which may be released to resolve an issue, but is suitable for multiple customers.
3. A Roll-up, which is a hot-fix that includes several fixes in one package.
4. An Update, which is a more major collection of changes and fixes, often containing some functionality change.
5. A Service Pack, which is a major change to the product, including fixes and usually major functionality changes too.
Many Microsoft products have hot-fixes released, and these are often not publicly available, but require a customer to contact Microsoft within a support-case to receive. The reason for this is that the fix may require personal attention and guidance by a support engineer because it has a specific installation procedure, or changes the way the product behaves in a way that is not suitable for the general public.
Until now, the UAG product-group has released Update 1, which was followed by Roll-up 1. A little later Update 2 has been released, and most recently, Service Pack 1 was released. Service-packs are cumulative, so SP1 includes all updates prior to it. This means that if your server is at Update-1 level, there will be no need to install Update 2 before installing Service Pack 1. Similarly, if your server has never been updated, you can go directly to Service Pack 1, with no need to install Update 1, Rollup 1 or Update 2. However, later on, If post-SP1 updates are released, they will not include the Service Pack itself, so you will be required to install SP1, and then the post-SP1 updates.
If you have installed a certain update, you may be wondering how to know at what level you are at. To know this, you can click on the Help menu, within the UAG management console, and select About.
