RDS Aurora 2.X extendedsupport

Question

I am looking at [this announcement](https://repost.aws/articles/ARBxrdllMWQGiUZDo9hidq8A/announcement-amazon-rds-extended-support-opt-in-behavior-is-changing-upgrade-your-amazon-rds-for-postgresql-11-database-instances-before-march-31-2024-to-avoid-potential-increase-in-charges)

```
October 31, 2024: Amazon Aurora MySQL 2.x will reach the end of standard support
October 31, 2024: Amazon Aurora automatically enrolls Aurora MySQL 2.x clusters in RDS Extended Support, which ONLY supports 2.11, 2.12 minor versions. To use Amazon Aurora MySQL 2.x past the end of standard support, you should plan to run your databases on one of these minor versions before October 31, 2024.
December 1, 2024: Amazon Aurora automatically charges you for RDS Extended Support.
February 28, 2027: End of RDS Extended Support for Aurora MySQL 2.x.
```

Does this mean we get one month "free" extended support and the charges only kick in for December 1st? Or on December 1st we get charged extended support for the previous month Novemeber?

re:Post Agent · Answer

Based on the information provided, it appears that you do get one month of "free" extended support for Amazon Aurora MySQL 2.x before charges begin. The timeline indicates that Amazon Aurora automatically enrolls Aurora MySQL 2.x clusters in RDS Extended Support on October 31, 2024, when standard support ends. However, the charges for this extended support do not start until December 1, 2024.

This suggests that there is indeed a one-month period (November 2024) where you will be enrolled in Extended Support but not charged for it. The charges kick in starting December 1, 2024, and will continue from that point forward. It does not appear that you will be charged retroactively for November.

It's important to note that to take advantage of this Extended Support, your databases should be running on minor versions 2.11 or 2.12 before October 31, 2024. If you plan to continue using Aurora MySQL 2.x beyond the end of standard support, you should ensure your databases are on one of these supported minor versions before that date.

Remember that while this provides additional time to prepare for an upgrade, it's still recommended to plan your upgrade to a newer major version (such as Aurora MySQL 3.x) well before the end of Extended Support on February 28, 2027, to avoid any potential disruptions or additional charges.
