@realact Hi, well yes and no, it's a bit of a story.
Every attempt failed which was taking up to 4-hours failed, and the support was not really helpful, in the end they just said it was my server/hosts. In the end, I thought it might be to do with the sheer size of 52GB. I could not see any other way than to tell the clone what not to copy over. I therefore downloaded most of the Technical data files to my local PC. These were unrelated to wordspress or the forum. They are schematics uploaded by my community for aiding electronic repairs.
This shrunk the clone from 52GB to 20GB. Now the clone appeared to work, and completed in under an hour. I got an automated email with links stating it was ready. I followed the links and after logging in found it had not really worked at all. My users appeared to be all there, but when I looked at plugins, there were loads of messages about missing plugins.
I contacted support but did not get any help, no response whatsoever. I started to install some missing plugins and the errors slowly started going. Then I got to the stage where I was to install wpforo version 2, and it all went pear shaped. You can read about that nightmare here.
After that, I deleted my clones and won't be using them again.
p.s.
After trying to get the clones working, it just kept eating my tokens, none of which were returned as the system decided they worked, when they had not.
p.p.s
Thank you for trying to help me, guess it does not always work out for some. I appreciate this is not my field of expertise, and they probably got fed up with me asking for help. In the end my main site got upgraded to V2 even if it did almost give me heart failure!
