“We are unable to offer hosting for Plusner sub-domains like
www.username.plus.com and ccgi.username.plus.com at this stage. We do plan to offer hosting for these names in the final product.”
Q: Does this mean specifically that my existing ccgi.myusername.plus.com space (which in turn has lots of subdirectories) will be transferable to the new space 'as is' and retain the ccgi.myusername.plus.com name (which is hard coded in those of my ‘Home pages’ pages which need to invoke call PHP)?
I know you can setup any subdomain you like on the trial platform.
So in theory, you can create a ccgi.username.plushost.co.uk area in the trial platform today using Plesk. The missing part is that your new webspace isn't YET able to be accessed by the username.plus.com bit... (instead using the username.plushost.co.uk).
As long as Plusnet are planning to make the username.plus.com domain structure be able to be applied to the new platform, then the ccgi bit could be done as well, I'm sure.
Clearly, you can't have that domain pointing to two places at once, so moving it over, would mean that the old ccgi & homepages would then cease to be addressable. So I can see that if this was offered, then it would have to be a choice to switch the DNS addresses from them over (maybe using the domains too in the portal), so that you chose when to migrate from one to the other. It would also have to be a reversible change, so that you could potentially switch it back again to the ccgi platform if your test website failed - (during the time the ccgi servers were still in service). This would give people a chance to check their website in good time, and switch the DNS when it was confirmed working.
Also the www homepages servers are not going to be decommissioned, so the www bit of username.plus.com if allowed to be moved, would have to be optional, since many would still want their hompages site to stay online. But since the servers for ccgi & www are currently split (on the same domain name), I can see no reason why they couldn't remain split (or both combined onto the new platform) as users saw fit. I think the www bit can already be optionally switched over to CCGI servers for those that request it. Basically it is a DNS change (as I understand it), so tools for self management shouldn't be too hard to code (hopefully!).
So that would be the needed features of creating ability to switch over the domain name. I can see a clear case for recommending that there is a method to move the username domains over (since many sites will be referenced & interlinked from outside websites that the user has no direct control over).
Hopefully, if it is not already in Plusnet's plan for the final platform, then it can be still added to that plan, before it is too late.
