Generalized steps:
# Deploy 8.6.0 with separate data directories, create a collection to prove it's working**
# download https://dist.apache.org/repos/dist/dev/lucene/lucene-solr-8.6.1-RC1-reva32a3ac4e43f629df71e5ae30a3330be94b095f2/solr/solr-8.6.1.tgz
# Stop the server on all nodes
# replace the 8.6.0 with 8.6.1 
# Start the server
# via the admin UI create a collection
# Observe failure warning box (with no text), check logs, find above trace

Or more exactly here are my actual commands with a checkout of the 8.6.0 tag in the working dir to which cloud.sh was configured:

# /cloud.sh new -r upgrademe 
# Create collection named test860 via admin ui with _default
# ./cloud.sh stop 
# cd upgrademe/
# ../8_6_1_RC1/solr-8.6.1.tgz .
# mv solr-8.6.0-SNAPSHOT old
# tar xzvf solr-8.6.1.tgz
# cd ..
# ./cloud.sh start

For those not familiar with it the first command there with cloud.sh builds the tarball in the working directory and then makes a directory named "upgrademe" copies it to "upgrademe" unpacks it, sets up a chroot based on the path in (already running separate) zookeeper, and by default starts 4 local nodes on ports 8981 to 8984 all with separate data directorys hosted under the "upgrademe" directory.
