In my Googling for an answer I found some earlier threads that might never have 
been resolved, but Florence asked some early questions that I thought I'd 
answer right now:
On ipa1 (original F21 server):

# rpm -qa | grep 389
389-ds-base-libs-1.3.3.13-1.fc21.x86_64
389-ds-base-1.3.3.13-1.fc21.x86_64
# ldapsearch -Y GSSAPI -h ipa1 -b cn=schema -s base -o ldif-wrap=no -LLL 
attributetypes | grep -i nsds5replicareleasetimeout
SASL/GSSAPI authentication started
SASL username: ad...@our.net
SASL SSF: 56
SASL data security layer installed.
attributetypes: ( 2.16.840.1.113730.3.1.2333 NAME 'nsds5ReplicaReleaseTimeout' 
DESC 'Netscape defined attribute type' SYNTAX 1.3.6.1.4.1.1466.115.121.1.27 
SINGLE-VALUE X-ORIGIN ( 'Netscape Directory Server' 'user defined' ) )

On ipa2c7 (new C7 server we're trying to add as a replica):

# rpm -qa | grep 389
389-ds-base-libs-1.3.10.2-10.el7_9.x86_64
389-ds-base-1.3.10.2-10.el7_9.x86_64
# ldapsearch -Y GSSAPI -h ipa1 -b cn=schema -s base -o ldif-wrap=no -LLL 
attributetypes | grep -i nsds5replicareleasetimeout
SASL/GSSAPI authentication started
SASL username: host/ipa2c7.wedgeofli...@our.net
SASL SSF: 256
SASL data security layer installed.
attributetypes: ( 2.16.840.1.113730.3.1.2333 NAME 'nsds5ReplicaReleaseTimeout' 
DESC 'Netscape defined attribute type' SYNTAX 1.3.6.1.4.1.1466.115.121.1.27 
SINGLE-VALUE X-ORIGIN ( 'Netscape Directory Server' 'user defined' ) )
