Main VE resources can be tuned as follows.
1. Edit your hosting plan(s) with new resources.
2. Upgrade all VEs subscriptions to this new hosting plan(s) (select a hosting plan, then set new "Non-Billable Resources").
3. Hosting plan -> "Subscription" tab Top > Business Director > Billing Manager > Hosting Plans > YourHostPlan Upgrade Status will show "Ready for upgrade"
4. Then go to Actions > "Upgrade" button and select All subscriptions or choose only needed ones. Press "Next" button.
5. Then you should synchronize Subscription.
Top > Business Director > Billing Manager > Subscriptions > Your_Subscription Button "Synchronize"
After this procedure your VE settings will be applied to your existing VEes with upgraded subscriptions.
