Don't worry about customizations to vb3 not upgrading - it doesn't matter if your plugins work, just that the attachment system is updated. Everything else is inconsequential. Don't try and actually run vb4 - just leave the database and import from it.
VB3-4 cli upgrade took 10 mins max - the db is on SSD's in RAID 1.
