09/18/2023, 6:06 PMhey all, my company's got metaflow deployed via cloudformation. looking at the published cloudformation template, it references python 3.7 and postgres 11. we got an email from AWS notifying us that we should upgrade.
python 3.7 was EOL earlier this year, AWS is ending support for 3.7 lambdas on Nov 27, and it won't be possible to update those lambdas after Jan 25. they recommend updating to 3.11.
AWS will be ending support for postgres 11 RDS in February. they recommend upgrading to postgres 14. taking a wild guess that yeeting 3.11 and 14 into the CFN is not a great strategy.
my question: is there a recommended upgrade path?

Worst case you can upgrade RDS from console and edit template later to match, so that cloudformation wouldn't try to do anything to it.

• can't do a major version upgrade to databases via CFN
• postgres 14 does not work with
