Hi Alfred,

Yes if you delete the cylc-run/u-dr920 directories on both PUMA2 and ARCHER2 and then try again with cylc8. I noted a few changes you’ll need to make to the suite in your other ticket. [Validity Time Mismatch](https://cms-helpdesk.ncas.ac.uk/t/validity-time-mismatch/1773) assuming you’ve not already made them since I copied your suite directory. 😁

Cheers,  
Ros.
