I’d appreciate a hint. On my old production system I am running all my operational suites with cylc-7.8.1 and rose-2019.01.0. These suites will soon move over to a new production system, where I will only install the latest versions of cylc-7.9.1 and rose-2019.01.3. To smooth the transition I would like to test the suites on the old system and upgrade everything.
In terms of software installation I have completed everything. On every system (old and new, cylc-hosts and HPC-hosts) the versions are reported as
$ cylc --version
$ rose --version
Rose 2019.01.3 (/opt/rose/rose-2019.01.3)
Now to my question. How do I upgrade the running suites with the least amount of disruption?
I stopped a suite and restarted it, but the suite still picks up the old cylc version:
$ rose suite-run --restart
[INFO] export CYLC_VERSION=7.8.1
What’s the best way to get the suite to pick up the new cylc-rose versions (which doesn’t requite a full stop/cold-start)?
