Migrating to a new CMS (Content Management System) can be a huge undertaking, compounded by ensuring that your data collection doesn't miss a beat. The purpose of this article is to provide a starting point of the questions to ask in preparation for migrating your Tealium instance into a new CMS. It's important to note that every situation will be different and you may want to consider a reimplementation.
1. Is there a Tealium Integration/Plugin for the CMS being migrated into?
2. Is utag.js running the latest version? If not, is there a plan to upgrade?
3. Ensure the data layer is consistent across the entire website, especially important pages, like the checkout funnel.
utag_dataobject is necessary, make sure to follow any changes downstream, such as variable names in iQ and attribute names in EventStream and AudienceStream.
4. Review all events.
5. Check all tags.
6. Check all extensions
7. Check Consent Manager.
8. Consider a Reimplementation.
