Couchbase Server 4.x Documentation?

I am looking for Couchbase 4.x documentation. I realize 4.6 is EOL. I checked the archive located here:

But when I click on any of the 4.x documentation, it just sends me to the 6.6 current documentation.

Hi there,
Thanks for reporting the problem.

Our archive of end-of-life product docs was moved to as part of the move to a new site engine for the docs,
…so 4.0, for example, is now to be found at

I’ve asked if that old page you were on can be either updated, or become a redirect.


Thank you Richard! I appreciate it.
