ASA-5525-X ASA and ASDM software upgrade version?

Have a 5525-X used as a perimeter fw and we want to update the software to the appropriate stable release.  We do not have FirePower.

 

Read the ASA Upgrade Guide and have looked at the various interim releases and I don't know which to select.  We plan to replace this firewall within the next year, so looking for the most stable interim release that will carry us through that period.  Does anyone have a recommendation for the ASA and ASDM software versions I should install?

 

In case it is a factor, we do use AnyConnect for about 20 remote workers.

 

Current state of ASA is as follows:

 

Cisco Adaptive Security Appliance Software Version 9.6(4)17
Device Manager Version 7.10(1)

Hardware: ASA5525, 8192 MB RAM, CPU Lynnfield 2393 MHz, 1 CPU (4 cores)
ASA: 4221 MB RAM, 1 CPU (1 core)
Internal ATA Compact Flash, 8192MB
BIOS Flash MX25L6445E @ 0xffbb0000, 8192KB

Baseboard Management Controller (revision 0x1) Firmware Version: 2.4

Hi,
The latest recommended gold star versions supported on your hardware are 9.6.4, 9.8.4 and 9.12.3. As you are running AnyConnect Remote Access VPN I'd recommend you running 9.12.3, as in versions 9.10 and later Cisco improved performance (ensure you are running AnyConnect 4.7 or later, ideally 4.9 in order to get the best performance possible).
