I must admit that this has been a little quirky in the past, but now that we've got all clients at 6.5.1 or higher it's been much better. The Upgrade Tracking database is pretty slick too, but we've only been able to get it working for 6.5.3 Clients or higher.
Notes 6.5.4 has been GA for 2 months now. Here are my client numbers:
- 6.5.4 - 47%
- 6.5.3 - 26%
- 6.5.2 - 16%
- 6.5.1 - 11%
As you can tell, we're doing fairly well with the upgrades.
