Need some suggestions regarding universal analytics and the new GA4.

Hello BHW,
It's been a roller coaster of the first month of the year for me. I was busy AF with work & family and barely got any time to surf BHW, but hey, I'm squeezing in any free time to learn a lot from BHW.

Firstly, I apologize if I'm posting in the wrong forums; in my defense, I'm unable to post anywhere else, and I couldn't find any relevant forum on which I'm allowed to post.

Now, making it brief, I want fellow members to show me some light on this Google analytics business. I currently do in-house SEO for a small outsourcing company with a static HTML website, nothing fancy. UA tags all the web pages, and the new GA4 property retrieves UA's data stream (Both are connected, I meant). The website is under renovation with content, keyword, design updates, and whatnot.

So, this brings me to my question - Should I use the old tags of UA on the new re-designed page? Or Should I Tag it with the new GA4 tag?

Again, I apologize if I'm posting this someplace I shouldn't. I look forward to clearing up my doubt and gaining more knowledge on this fucked-up GA4 shenanigans.

C'mn guys please help me out.

To migrate Universal Analytics (UA) tags to Google Analytics 4 (GA4), you need to follow these steps:

1. Set up a GA4 property: Go to the Google Analytics admin panel and create a new GA4 property.
2. Tag your website: Implement the GA4 tracking code on your website. This code will enable GA4 to collect data from your website visitors.
3. Migrate your data: If you already have a UA property, you can import your data into GA4 using the GA4 data import feature. This will allow you to carry over your historical data to your new GA4 property.
4. Configure your events: In GA4, events are used to track user interactions with your website. You need to identify and map the events you want to track in GA4 and configure them in the GA4 property.
5. Verify the implementation: Verify that GA4 is correctly collecting data by using the GA4 real-time report and checking that events are being recorded.

Note: Migrating to GA4 may require changes to your tracking code and data collection strategy, so it is recommended to thoroughly test the implementation before fully switching over to GA4.
