I guess it might be reasonable to concentrate first on the links with math.uga.edu/~pete which were skipped by the Community User.

A: Suggestion to mass-replace links to http://math.uga.edu/~pete

How to check which posts were edited Probably some user want to check which posts (in general or their own posts) were influenced, so that they can see whether they were some negative side effects. You can look at the recent edits on the Community User's profile page You can use SEDE - for examp...

(In the post above, there is a section: "Posts where old links remained".)

And perhaps after that we could look into links that were edited by the community user - but there might be some other problems:

Let us collect in this community wiki answer the posts which might need manual editing after the bulk conversion is done. Links which are dead both now and after the transformation The links to the files 243functions1.pdf, 243functions2.pdf, 243integrals1.pdf, 243integrals2.pdf, 243series4.pdf, ...

This post contains http://Sieve%20of%20Eratosthenes. Do you think https://en.wikipedia.org/wiki/Sieve_of_Eratosthenes was intended? Or something else?

A: Is that true that all the prime numbers are of the form $6m \pm 1$?

Let $A = \{2n \, | \, n \ge 2\}$. Let $B = \{3n \, | \, n \ge 2\}$. Let $C = \{n \in \Bbb N \, | \, n \ge 2 \} \setminus (A \cup B)$. It is evident that any prime number must belong to the set $C$ (c.f. the Sieve of Eratosthenes). For $-4 \le k \le 1$ let $D_k = \{6n + k \, | \, n \ge 1\}...
