07/09/2024, 9:51 AMā¢ Hello, using GrowthBook v2.9.0 here
ā¢ Is there a way where I can force an experiment to use hashVersion 1? I can't seem to find the selection in the new / edit rule form.
ā¢ This might sound strange, but intention here is smooth migrations from older SDK that supports only v1 to latest SDK version, out of concern that v1 and v2 allocation could produce different variations

Good morning and thank you for writing in.
Please can you confirm which SDK you are using?

07/10/2024, 7:54 AMHi Albert, sorry the hashing is SDK dependent so I will need to know the SDK name (not just the version). Please, can you confirm which SDK you are using so we can further investigate? The SDK language will render on this page - https://app.growthbook.io/sdks
Looking forward to your response :)

07/10/2024, 8:22 AMHi Albert, thank you for your response and assisted information.
The ability to edit the hash version was introduced just over 2 weeks ago.
For new experiments created, able you able to now change the hashing version to v1?

07/10/2024, 8:31 AMā¢ hi again @flaky-noon-11399 for following this up ..
ā¢ but as can be seen in my second screenshot, which is still using 2.9.0 instead of 3.0.0, i can see the selection of

07/10/2024, 8:36 AMI even tried lowering my sdk connection version to 0.20.0 in hope to see the selector, because of this PR: https://github.com/growthbook/growthbook/pull/2097 .. but in vain

07/10/2024, 9:14 AMHi Albert, sorry there may be some confusion here. It's SDK-dependent, not experiment-dependent, whether or not v1 or v2 hashing is available, nor is it GrowthBook version dependent.
To make sure we are aligned, please can you take a screenshot of the SDK connectors page?

07/10/2024, 3:02 PMHi Albert,
Please can you confirm the following:
1. Are you self-hosting or cloud-hosting?
2. If self-hosting, are you running GrowthBook 2.9? (If so, why not 3.0?)
3. Which version of the Node SDK do you want to be using, and which are you using currently?
4. Are BOTH of the experiments using the same SDK Connection? Please can you double check this?
5. Are BOTH experiments using the same targeting attributes?
6. Please send us a screenshot showing which button or link you're clicking on in the ā`bert-1`ā experiment to open the "Edit" modal.
7. Please send us a screenshot showing which button or link you're clicking on in the ā`another experiment`ā experiment to open the "Edit" modal
8. A screenshot or code snippet of how you have the Node SDK integrated in your application

07/11/2024, 4:14 AMā¢ hi @flaky-noon-11399, thank you so much for your help.
ā¢ Ok, let me find a time to try this on 3.0.0 and see how
ā¢ But probably not soon, because i've found a way to downgrade it to hashVersion 1 through REST endpoint ..
