TYPO3 CMS 8.7 Jquery errors after moving site

Question

Recently I've moved one of my development sites into production. The following steps were taken.

Complete backup of both versions (4.5 & 8.7)
Removal of old version
Uploading new TYPO3 developed version
Updating database connection in the LocalConfiguration file

After doing all this and enabling the install tool I am able to login to my install tool but not into the backed. Both the install tool and the backend are giving the following error.

Uncaught SyntaxError: Invalid or unexpected token on Jquery. Various other errors also appear because of this. Included below is a screenshot for completion.

No file transfers failed and I am unable to login to the backend. I haven't done anyhthing to the database apart from setting it up

Open jquery-3.2.1.min.js and look if something is odd there. — Ulrich Thomas Gabor
@GhostGambler I've looked there and deleted the file as well, when a new one was obtained it stil gave me the same error — RDAxRoadkill
Did you cleared the caches? Deactivated all extensions? Checked the setup in the Install Toolß — Thomas Löffler
You mean before movement? Or after the fact? I did clear the caches, but I didn't deactive any extensions. What should I lookout for in the install tool — RDAxRoadkill

It's possible that file-compression was activated for JS- and CSS files which doesn't match the settings on the new server. If you click in the browser-console on a file-link you get some output like this:

You can adjust the compression-level in install-tool but can see the value in the file typo3conf/localconf.php (for TYPO3 4.x) or typo3conf/LocalConfiguration.php (for TYPO3 8). It might currently look like this:

$TYPO3_CONF_VARS['BE']['compressionLevel'] = '9';

and you can adjust it just to 0:

$TYPO3_CONF_VARS['BE']['compressionLevel'] = '0';

In the install-tool of TYPO3 4.5 the option looks like this:
