My Google Analytics codes are implemented via Google Tag Manager. However, I'm trying to upgrade to Universal Analytics.
According to Google's guide on switching from Classic to Universal via Tag Manager, it says you have to create a new tag and rule, and delete the old ones (https://developers.google.com/analytics/devguides/collection/upgrade/reference/gtm).
However, when I'm in GTM, I seen an option to edit the Tag Type and switch it to Universal Analtyics. The question is: Can't I just switch the tag type to Universal, plug in the new ID, and it would function properly?
