Migrating from a client-side GTM setup to server-side is a significant but high-value change. Done wrong, it can disrupt campaign data for weeks. Done right, it permanently improves conversion capture rates and data quality. Adslytics manages GTM migrations with a phased approach — parallel running, tag-by-tag verification, and deduplication — so you never have a data gap.
