Actually I was using the below command to check the compatibility, it worked without any issue with 12.6 but it is not working with 1version 2.14

Just in case I'm _not_ misreading this... are you saying you already ran this command once with postgres v12.6?

If so, since you've used --link the original folder will no longer be version12 data.
