Hi Marcel - thanks for responding...

resources of ClearCenter at the moment are very limited

What resource is "very limited" specifically? One that would make sense is they cannot afford the migration. There are hundreds of sites running good forum software, so the expertise is out there for ClearOS to engage. If this isn't the case, then please detail what the lacking resource is...
Last time I looked at the ClearOS Discouse link - there was no obvious evidence of any progress since the initial creation activity around April/May last year.
