#
# When the group is in **single-primary** mode and the user causes a
# change to **multi-primary** mode the group must:
# - 1: Update everywhere checks must be set to True on all members.
# - 2: All members must be writable, so read_only mode should be False
# - 3: When all members are writable, any transactional conflict must abort
#
# Test:
# 0. This test requires two servers in single primary mode
# 1. Create table to test the transaction conflict
# 2. Execute action to switch to multi primary mode
# 3. Assert on server2 that super_read_only is disabled and
# group_replication_enforce_update_everywhere_checks is enabled
# 4. Assert on server1 that super_read_only is disabled and
# group_replication_enforce_update_everywhere_checks is enabled
# 5. Execute two transactions in parallel and confirm that will trigger
# a conflict
# 6. Cleanup
