Migrating jQuery from 1.4 to 3.0 -


i saw jquery has jquery-migrate script safely upgrade jquery. have 2 jquery-migrate repos: 1. https://github.com/jquery/jquery-migrate (for migrating 3.x) 2. https://github.com/jquery/jquery-migrate/tree/1.x-stable (for migrating 1.9)

is necessary first migrate 1.9 , 3.x, or can include first script in website, , migrate 3.x directly? 3.x migration script not notify when apis removed in 1.9 used?

this 1 of links provided: https://github.com/jquery/jquery-migrate. can find paragraph in link provided in question:

note: upgrade jquery 3.0, first need version 1.12.x or 2.2.x. if you're using older version, first upgrade 1 of these versions using jquery migrate 1.x, resolve compatibility issues. more information changes made in jquery 3.0, see upgrade guide , blog post.

since want migrate jquery 1.4 3.0, , based on official documentation says, first need version 1.12.x or 2.2.x if plan use jquery migrate 1.x resolving compatibility issues.
