Redirect 2.x and 3.x page visitors to 4.x/latest docs #446
Description
Search engines often present search results with links to OpenEBS v2.12.x docs or v3.x docs. This might lead a new user to archived storage plugins. This could be fixed if these pages visits redirect users to v4.x.
This might require a separate section/location for v2.x, v3.x docs.
