Algorithm compatibility between BIND 9.6.2 and 9.16

I am new to BIND installation and configuration.

We have been using a set of BIND 9.6.2 servers (one is master & other 
one is slave) running on Fedora Core 10 with algorithm as 'hmac-md5'  
for transferring zones and other DNS related data between Master-Slave. 
These BIND 9.6.2 server set was installed and configured by my 
predecessors for the domain ''(let us say)

Our domain got changed recently to '' and and i setup newly 
released  BIND 9.16 on CentOS 7.6 for this domain as authoritative NS 
and is working perfectly without any issues.

For somtime we would like maintain both the domains '' & 
'' and  planning to configure '' zone as slave in 
the new 9.16 server.

I would like to know the support of algorithm 'hmac-md5' in the new 
release of BIND 9.16 for making the zone tranfer '' between 
the old master and new slave.

If this algorithm is not supported, please let me know if any work 
around is possible to make the new BIND 9.16 as slave to 9.6

Any help is greatly appreciated

Thanks in advance
