We upgraded an MX480, with a subscriber management license, a few months ago 11.4X27.42 to 12.3R10.2 without any issues.
The 'Upgrade and Downgrade Support Policy for Junos OS Releases' section discusses what's supported, and it's not clear without further research if a 11.2 to 12.3 upgrade would be supported. TAC would be your best resource to find out. My guess is your primary risk would be the inability to perform a downgrade, or configuration after upgrade not being correct, but that's speculation.

Hello, So i am running a MX with 11.2 and have finally been able to schedule a long overdue software upgrade. Issue is the oldest still available on Junipers site is 12.3. I understand the recommended upgrade paths would prefer i go to 11.4 first, then 12.3 then to 13.3 which is where i would like to end up. My question is, can i go from 11.2 to 12.3 or even direct to 13.3 without breaking anything? What are my risks? Configuration and features are very basic.
