Have to move off Arvixe NOW -- Linode? Digital Ocean? Other?
Jamroom Hosting
Well, this could have been a real problem - but was patient and I worked it all out.
I initiated the transfer request and got an email back from Arvixe saying that I was using too much disk space (on an UNLIMITED account) and I was storing backups on the server against their Acceptable Use Policy.
It turns out that the directory with the Jamroom install had about 34GB in it and the Softaculous backup folder was about 37GB. I deleted the Softaculous backup and ran the the Delete Media tool (my browser crashed towards the end of that process but everything appears to be okay - I think the process was still running on the server, anyway, by the time I got the browser reloaded and I re-ran the tool everything was clean) and then manually deleted all of the /cache folders and got it down to a tad over 28GB. Crazy. There was only 12GB in my Ning archive.
So, the Arvixe tech support guy on the phone (which is cool - it is almost 02h00 here) got the person who's going to do the transfer on the phone to make sure I wouldn't get another email saying I was still using too much disk space on my UNLIMITED account. I just hope it happens quickly (gigabit ethernet between boxes too much to hope for?) so I can update the DNS soon.
Setting an alarm for an hour from now to see if the email has come that the Xfer is done with the IP address I need. And then it's crossed fingers to hope that performance improves enough to make the whole process worth the effort.
