We have staged SOLR 6.x and 7.x environments with ZK V3.5.5 as requested and

The ZK project has documentation about backward compatibility:
https://cwiki.apache.org/confluence/display/ZOOKEEPER/ReleaseManagement
This says that 3.4.x and 3.5.x should be compatible.
There may be configuration changes required to get them working. When
we upgraded ZK to 3.5.5 in Solr (which was done with SOLR-8346 and
released in version 8.2.0), we found that running Solr against a 3.5.5
server required adding this line to the ZK server config:
4lw.commands.whitelist=mntr,conf,ruok
When you say that it doesn't work, can you tell us EXACTLY what doesn't
work? Ideally, you'll be able to let us know what errors are being logged.
Thanks,
