Do logical cores have to be in place before upgrading 2021.4 to later versions?

[David-Carnes]

Subject line says it all.
Follow up question:  Can I jump to 2023.2 or should I upgrade in increments?  

Many thanks for y'all's  replies.

Hi @David-Carnes ,

Not sure I understood your question, but I will answer anyway 😀 Maybe you saw a document mentioning the AMP engine requiring more cores for optimal performance but that is not mandatory. I have seen companies using only 4 physical / 8 logical cores with the AMP engine on and that is fine as long as you don`t have lots and lots of concurrent workflows.

As for your second question, the short answer is yes. There are lots of moving parts when upgrading your server and I will share some important links for you to have before doing so. (not sure if you need it but leaving it all here for others as well)

1. MongoDB upgrade best practices: https://help.alteryx.com/current/en/server/best-practices/mongodb-in-server-upgrades-best-practices....
2. PreUpgrade Checks (guarantees your service will restart after the upgrade): https://knowledge.alteryx.com/index/s/article/server-pre-upgrade-checks
3. MongoDB schemas - related to your question, you can never jump MongoDB versions; in your case, you are going from 4.2 to 6, which is ok. IF you were on 21.3, you would be required to have an intermediate upgrade so your MongoDB doesn`t skip versions (4.0 > 4.2 > 6.0)

4. Important stuff to be aware: https://help.alteryx.com/current/de/server/install/install-or-upgrade-server/version-to-version-serv...
5. Upgrade checklist: https://help.alteryx.com/current/en/server/install/install-or-upgrade-server/server-upgrade-checklis...
   1. IF your server has custom R and Python libraries, you will have to list and reinstall them
   2. Same for non-native-python-based connectors, you will have to check if reinstalling is required:
      1. https://help.alteryx.com/release-notes/en/version-support-policy/alteryx-embedded-python.html#python...
6. Since Alteryx changed its encryption layer on 22.3, there is an additional tool/step called the migration prep tool that will run during the installation. I`m mentioning this because, depending on your server size, this could take a long time to execute.
   1. https://help.alteryx.com/current/en/server/install/install-or-upgrade-server/migration-prep-tool.htm...
   2. https://help.alteryx.com/release-notes/en/release-notes/server-release-notes/server-2022-3-release-n...
   3. You have the option to run this part before the upgrade day
   4. After the upgrade, designers on version lower than 23.2 won`t be able to publish workflows, so all designers must be upgraded as well 

Apologies for the long answer. Hope this is helpful.

Best,
