DPM/SIM Fingerprint Expiration - Yes/No Question

Hi,

 

I am helping someone with a SIM integration. I am upgrading them from md5 to sha512. The response validation needs to be updated within 10 days, but per this post-

 

https://support.authorize.net/s/article/Do-I-need-to-upgrade-my-transaction-fingerprint-from-HMAC-MD...

 

The fingerprint also needs updated, although no end of life is explicitly given. I am prioritizing my work, and would like to know if the md5 fingerprint will still be accepted until at least 4/30/2019. 

 

Can someone on the authorize.net team answer with a quick yes/no? 

 

Thank you very much for your excellent products and support.
