Citrix Licensing server upgrade

To make this as brief as possible, I wish to apply hotfix rollup 5 to my Citrix Presentation Server 4.5 farm.  In order to do so, the licensing server apparently needs to be updated to 11.6.1 or higher.

Checking the licensing server, as found here, http://support.citrix.com/proddocs/index.jsp?topic=/technologies/lic-find-doc-by-version-c.html , there is no administration tab as listed, I just figure the version type is pretty old, so I navigate through the regedit method.  

The registry key lists my version as 4.5.0.  

I have downloaded the 11.6.1 msi, but before I run this, I wanted to check in and ensure that I am not going to completely jack my license server (and therefore, the farm) by upgrading directly.  I don't seem to see any documentation on this, so I figured I should check with someone with extensive Citrix knowledge before proceeding.

If it makes any difference, all servers are 2003 sp2.

TIA

License server upgrade is very painless, easy to do and takes les than a minute.

There are two ways you can do this:

1.   Install 11.6.1 on top of what you have and maintain all settings, users and license files.
2.  Uninstall the current product, install 11.6.1, reinstall all license files, resetup all users and any settings you had in the previous version.

I would opt for #1 myself.  I have done this more times than I can count and have never had an issue.

Great, that's just what I was hoping for.

On a bit of a side note, if you happen to know, the farm has hotfix rollup 2 installed.  I can't seem to find 3 or 4 to download, any issue going straight to 5?
