It was not meant to be a final answer, but rather a list of questions for you to answer in order for me to provide you a detailed answer.
I need to know your sensor models and versions in order to let you know specifically what packages you need to download and install.
If you are using an IPS-4260 it is a different set of packages than if using other sensor models, but only if staying at version 5.1. If going to 6.0 or 6.1 it uses the standard packages instead of special ones.
If you were running 5.1(6)E2 versus 5.1(7) then it is a different set of files as well.
From 5.1(6) you had to upgrade all the way to 5.1(8)E2. If running 5.1(7)E1 then you could just upgrade to 5.1(7)E2 OR to 5.1(8)E2.
If you try going to 6.0 or 6.1 it is again a different set of packages.
Based on your latest response I assume you were able to figure it out.
As for upgrading to 6.0(5)E2 and/or 6.1(1)E2 it once again depends on your specific sensor models.
If using IPS-4210, then NO you have to stay at version 5.1(8)E2. The IDS-4210 is not supported in 6.0.
If using IPS-4215, IDS-4235, IPS-4240, IDS-4250, IPS-4255, IPS-4260, IDSM-2, NM-CIDS, SSM-10, or SSM-20; then yes you can upgrade to 6.0(5)E2 (assuming you have an up to date contract).
If using IPS-4240, IPS-4255, IPS-4260, IDSM-2, SSM-10, or SSM-20; then yes you can upgrade to 6.1(1)E2 (assuming you have an up to date contract). The IDS-4215, IDS-4235, IDS-4250, and NM-CIDS are not supported in 6.1.
