Convert Addon Domain to Account Workflow Issue

Hi Guys,
Was about to post this in the feature requests section; but thought its more of a bug than a feature request really so came to the forums to post it as I dont think you have a dedicated bug report system.

Problem:
Addon domain was converted and assigned a plan that had 1GB of disk space. Problem was that the account actually used up about 1.7GB of disk space. There was no easy way to check this otherwise I would of assigned a bigger plan from the get go.

Result:
Transfer commenced and "completed successfully", that is to say, it was no longer in the previous account as an addon domain. Having said that; the addon domains directory was still in the origin /public_html/ as well as /mail/ directories and its contents hadnt been moved (probably others as well, but thats what I picked up).
I had to end up upgrading the destination account; then manually moving the directories over and chowning them. Then re-creating the mailboxes in cPanel and luckily it picked up the existing contents.

Proposed Solution:
- Simply advise that the addon domain requires "X" amount of resources.
and/or
- Don't allow the the user to continue without selecting a plan with appropriate resources
or
- Move everything across regardless of quota and just let the account over-use for the sake of the transfer; (in this case, 1.7GB / 1GB used).

Thanks.

 

Thanks @cPWilliamL - much appreciated and will do so in the future!
