HI,guys     Can I use M1 module with F3 module together in the default vdc?

I notice the last date of support for the ACS 5.4 is Mar.18 2018.Does it mean that after Mar 18 I couldn't open a case for it? This is the official link: https://www.cisco.com/c/en/us/products/collateral/security/secure-access-control-system/eos-eol...
