# OBJECTIVE: 
# In Autosubmit 2.x experiments three projects were cloned (model, templates and ocean_diagnostics).
# New Autosubmit 3.x experiments only allow cloning one project (auto-ecearth).
# Auto-ecearth is a single project containing model, templates and ocean_diagnostics among others.
#
# This script covers the need of having to run an Autosubmit 2.x experiment with Autosubmit 3.x.
# It assumes that no auto-ecearth available version can reproduce what the old experiment was doing,
# and it adapts a copy of that old experiment, reshuffling the configuration files and removing 
# unnecessary variables from the old templates to adapt them to the Autosubmit 3.x framework.
#
# DESCRIPTION:
# This script will modify and adapt the experiment configuration file of the TARGET_EXPID
# according to Autosubmit 3.x standard.
#
# This script will also clone model, templates and ocean_diagnostics
# from ORIGINAL_EXPID into TARGET_EXPID "proj" folder. 
#
# This script will also remove unnecessary template header/tailer variables.
#
# USE:
# 1st step
# --------
# Before executing this script you must use the copy option of Autosubmit 3.x
# e.g. autosubmit expid -y i000 -H ithaca -d "copied from original i000"
#
# 2nd step
# --------
# ./migrate_exp.sh ORIGINAL_EXPID TARGET_EXPID
