You shouldn't have any issues, just follow the steps documented in the release notes.

All good questions, I have a pretty good prcedure but we have a spare set of appliances we run our upgrades on using the original UCS files. The only way for sure to know if your scripts are still there will be to do a test upgrade or upgrade the standby and give it a good checkout. I can share my upgrade instructions if you let me know where to send them or post them. Our last upgrade was from 11.2 to 11.5.1 so it should be similar. I can tell you if you are using any HTTP classes you have to get rid of them before you upgrade or you will have several problems. Tiy can create the new boot volumes directly from the Hot fix image on the standby to be safe.

I was going from 11.4 to 11.6, but it's probably very similar. One problem I had was I had to resize the MD1 volume. This may be particular to my hardware (not sure) but doing the following resolved the issue:

modify /sys disk logical-disk MD1 vg-reserved 10000

This was the error in question:

: "/usr/bin/tmsh -n -g load sys config partitions all" - failed. -- 01071008:3: Provisioning failed with error 1 - 'Disk limit exceeded. 16188 MB are required to provision these modules, but only 0 MB are available.' . Unexpected Error: Loading configuration process failed.

I had plenty of available disk.

Hello afedden, we are preparing to upgrade our LTMs from v 11.3 to 11.6. I would be interested in taking a look at your upgrade testing documentation if you are willing to share. We have an active/standby VE pair I can use for testing.
