Oracle Database 21c is here - Innovation Release

Oracle Database 21c is the latest innovation release of world's most popular database. Oracle Database 21c is initially available on Oracle cloud with Autonomous Database Free Tier and Database Cloud Service.

You can directly upgrade to Oracle Database 21c from the following releases:
- Oracle Database 19c
- Oracle Database 18c
- Oracle Database 12c Release 2 (12.2)

Oracle Database Innovation Releases include many enhancements and new capabilities which will be included in the next Long Term Release. Oracle Database Innovation Releases does not have extended support. As Oracle Database 21c is also an innovation release, which means it will only have 2 years of premium support. 

Oracle Database Long Term Releases usually have 5 years of Premier Support followed by 3 years of Extended Support. Personally I would not like to upgrade my production servers to an innovation release (Oracle Database 21c). I would like to upgrade (or stay with my Oracle Database Server with Oracle Database 19c which has Premier Support till April 30, 2024 and after that Extended Support will start for Oracle Database 19c.
