greenman, in MariaDB 10.2.13 I replaced the links for which you named replacements. The following remain for now:

dbug-package.html
innochecksum.html
innodb-troubleshooting.html
innodb-troubleshooting-datadict.html
error-creating-innodb.html
upgrading-downgrading.html

Also windows-symbolic-links.html

innochecksum.html -> https://mariadb.com/kb/en/library/innochecksum/

Replacements:

• InnoDB Troubleshooting, we have the general category page here and the specific data dictionary page here.
• Our pages on upgrading live here, the specific link would depend on the version in that category.

Otherwise:

• There's currently no dedicated page on the dbug package, parts are covered in the Connector/C and on creating trace files.
• There's no dedicated counterpart to `error-creating-innodb.html`.
• According to this, we don't support downgrading, but you might want to link to it since it gives an overview of how to go about moving down a version.

I've taken control of this ticket in consultation with Marko and Ian.

The windows-symbolic-links.html only appears in a source code comment, so we can ignore that one.
The message string that was referring to error-creating-innodb.html was never output. I removed it.

git grep -liw dev.mysql.com will still returns a number of references, including one in COPYING.thirdparty. Perhaps we can ignore the matches in mysql-test, but I think that the following should be reviewed, possibly as a separate bug, by jacob.moorman:
