GA4 is one of the easiest tags to migrate to server-side, and one of the most rewarding when you do.

The short version: gA4 reports that match what you actually shipped is mostly a matter of doing the obvious thing carefully. Add the GA4 client to your server container, point your existing GA4 tag at the new endpoint, and let it run in parallel for a week before cutting over.

Some of your custom configurations will need re-parameterising. Plan an afternoon for it. That trade-off is the one most teams underweight when they plan the work, and it is the one that quietly determines whether the project ships on time.

If you want a longer treatment, we have a deeper post in the series. For now, the takeaway is small enough to fit on a sticky note: Once GA4 is server-side, every other Google product you bolt on inherits the same advantages with very little extra work.
