Upgrading from 4.012 To 4.0.20

[hotrod]

I'm rebuilding Our J3 To J4 and Migrated VM  over to 4.012   Having some issues with a few things .. Like editing orders..   I should be using the latest and greatest VM.. before I start asking for help and I have no issues paying for this..

I have the Dev site in a sub domain.. do I need to add that domain to the domain I'm purchasing Under?   Or can I use my main domain.. The site will be loaded to when I'm done..

also. any tips on install?..  download package and upload like everything else?

You can enter the final domain if you wish, and wait to enter the membership number on the final site.

You can install like any other update onto a copy of your existing site in a subdomain.
