My preferred cutover date is not available
Answer ID 10933   |   Last Review Date 06/17/2026

Why am I unable to select certain dates or times while scheduling an Oracle B2C Service update cutover?

Environment:

Oracle B2C Service, Site Update, All versions

Resolution:

Cloud Configuration Assistant only displays available dates and times. A customer’s preferred cutover date and time may not be visible in Configuration Assistant for the following reasons:

  1. Another customer hosted in the same data center scheduled their cutover for that date and time
  2. Regular weekend maintenance or long-term maintenance of Oracle data centers is scheduled
  3. Oracle Corporation blackout periods coinciding with company holidays

 

Cutover Blackout Period (all in US Pacific time PST/PDT):

All day 1st & 3rd Friday 00:00 - 23:59, 2nd & 4th Friday 12:00 - 23:59 plus the 1st and 3rd Saturdays (exception applies) 00:00  - 12:59, except the 5th Friday of the month (e.g. no maintenance on 31 January 2020)

 

2026
  • 1 January 00:00 - 5 January 23:59
  • 23 May 00:00 - 25 May 23:59
  • 3 July 00:00 - 5 July 23:59
  • 5 September 00:00 - 7 September 23:59
  • 26 November 00:00 - 30 November 23:59
  • 25 December 00:00 - 31 December 23:59
2027
  • 1 January 00:00 - 3 January 23:59
