(Note: British English says eh? "This common British construction is not strictly incorrect in American English, but it is generally avoided, especially in formal writing." https://www.lexico.com/en/grammar/that-or-which).
For the rest of the world: I disagree. They can have the same meaning, but I don't think it works here as the sentence is currently written.
Here's an easy way to remember the difference between that and which: If removing the words that follow would change the meaning of the sentence, use "that." https://www.quickanddirtytips.com/education/grammar/which-versus-that-0
Remember, which is as disposable as a sandwich bag. If you can remove the clause without destroying the meaning of the sentence, the clause is nonessential and you can use which.
We don't "do" changes, we make changes. The past tense of make = made.
