How long must I wait before requesting another update?
Updates, All versions
When requesting an update there are designed waiting periods in the process. This ensures adequate time to evaluate your upgrade test site and production site throughout the process, as well as allow system processes to fully execute.
Requesting an update immediately after another update: After your site has updated, there is a short window where you will be unable to request another update. From after the first weekend (US time), after 4 days have passed since the most recent update was completed.
