If you have UCSS, you can order upgrades from Cisco via the PUT (Product Upgrade Tool).
If you don’t, you will need to purchase the upgrade. You will get an upgrade license to add to your existing ones, and a media kit that allows you to upgrade. Someone else might like to give you some advice on what parts etc you wish to order, or speak to your Cisco sales guy.
When it comes to doing the actual upgrade, you'll find you need to go through several 'hops' to get to the intended version. The following page lists supported upgrade paths. You'll find that you'll probably need to upgrade to a newer version of 5.x, then upgrade using the media kit to a 7.x release, then perhaps apply another 7.x release to reach your intended final version. It really depends what Cisco ship you when you order the upgrade.

This will result in mandatory memory and hard drive upgrades if older supported servers are desired for use with the new software versions.
You don't meet the HDD requirement. You have 40GB HDD.

No. You will only need the SRST licenses on the primary router. Because this feature...
