HotFix installation question

Question

It's been a couple years since I've had to do any kind of code upgrade on an f5 ltm pair. So here's my current situation:
2 F5 LTM 3900s set up in Act/Pass pair, currently running LTM v11.3.0 build 3093 installed on volume 1.2. Both devices need to be upgraded to 11.4.0-20405-HF2. 
The hotfix image has been imported, but not installed, on both devices. &nbsp;
Basically, I'm looking for a walkthru/refresher on the upgrade process.&nbsp;
Thanks in advance.&nbsp;

Your best bet is following instructions in release notes - http://support.f5.com/kb/en-us/products/big-ip_ltm/releasenotes/product/relnote-ltm-11-4-0.htmlrn_install_overview. You will need to upload the full 11.4.0 release to the LTMs, too (HF is only a roll-up of hotfixes for the main release). &nbsp;
A few other tips:&nbsp;
upload a current qkview to ihealth and review any notices that could impact your upgrade (for example, httpclass profiles go away in v11.4+)open a proactive support case before your upgrade (~1 week in advance) in the event you have upgrade issues
