This is also from the same release notes which are attached.
Upgrading from 3.x to 6.1.x
If you are running ArubaOS 3.4.4.1 or a later version in the 3.4.4.x code stream, you can directly upgrade to ArubaOS 6.1.2.8. However, upgrading from a 3.x ArubaOS version earlier than 3.4.4.1 requires an upgrade hop. You must first upgrade to the latest ArubaOS 3.4.4.x build before upgrading to ArubaOS 6.1.2.8.
There are lots of helpful tips on the upgrade procedure in there too.
Jrwhitehead You are absolutely correct. The person who opened this thread only said 3.4 and did not say if it was 3.4.4.1, so I was just being cautious.
There are two reasons for the double upgrade in the first place:
1. In older versions of code, the access points had a fixed limit in software about the size of an image they would download. At a certain level of code, this was exceeded. This means that those APs would have to first be upgraded to a version of code that removed the limit, and then upgrade to a version of code that was larger than the limit.
2. In ArubaOS 6.1 and above, there is an additional Ancillary Partition that has files for the new Dashboard that need to be installed to the correct partition and this needs to be prepped before upgrading to 6.1.x
Here are the issues you are primarily trying to avoid:
1. You could theoretically go from any version of code to 6.1.2.8, but your access points would not allow the larger image to be downloaded to the APs, and you would be stuck in the water
2. You could theoretically go from any version of code to 6.1.2.8, but the ancillary partition would not have been loaded onto the controller and you would get a message at the login screen saying "An additional upgrade is needed"
