###############################################################################
# Validate that on a group mode change from multi to single-primary,
# the primary shall override the replication failover channels configuration
# on all group members.
#
# Test:
# 0. This test requires three servers
# 1. Deploy a group in multi-primary mode on server1 and server2.
# 2. Configure a failover channel on server1 that replicates
# from server3.
# 3. Configure the same failover channel on server2.
# In single-primary mode, the mode to which we will change,
# the failover channels must exist on all members.
# The channel is created with SOURCE_CONNECTION_AUTO_FAILOVER=0
# to show that it will change to SOURCE_CONNECTION_AUTO_FAILOVER=1
# when group mode changes to single-primary mode.
# 4. Add some failovers sources to server2 that will be replaced
# when server1 becomes the primary in single-primary mode.
# 5. Change to single-primary mode.
# The primary must be server1, since when a member has
# replication channels running it must be the primary.
# 6. Validate that server1 replication failover channels
# configuration is preserved, and that it did replace the
# one on server2.
# 7. server1 leaves the group.
# server2 is the new primary and does start the failover
# channel.
# 8. Clean up.
