# Prerequisites for migration:
# - Previous version of core, ui, and mongodb containers should be running
# - Current working directory should be the one with the docker-compose.yml
# - Mongo mount path specified in the docker-compose.yml should be a
# non-existent directory.
#
# Executing the script:
# > chmod +x migrate.sh
# > ./migrate.sh
#
# Notes:
# - After migration, all the Netskope plugins would default to poll interval
# of 60 minutes. Update this manually from UI if necessary.
