Migrating sGTM hosting sounds complicated, but it isn't. If you have Stape with one container ID and 3–5 platforms (a typical CZ store), it's 4 hours of work + 5 days of parallel running for validation. Here's the process we use in Care.
When it makes sense to migrate
- You pay in USD and want an invoice in CZK with ISDOC
- You need Sklik or Heureka (Stape supports neither)
- You want EU-only data residency and CZ support during business hours
- You want to save 10–15% with no loss of capacity
When not to migrate
- You depend on the Stape Store NoSQL DB with 1000+ keys
- You need a dedicated IP or a HIPAA BAA (the DataNostro Custom plan can do it, but it's a design conversation)
- You manage a mobile SDK + Stape iOS / Android — DataNostro doesn't have an SDK yet
Step 1: Inventory
Export from Stape:
- The Container ID (Stape shows it in the dashboard)
- The tracking subdomain (e.g.
track.store.cz) - Platform configs — Pixel ID, Access Token, GA4 Measurement ID, etc.
- Power-ups settings — Cookie Keeper, Custom Loader, Anonymizer rules
- API keys (Klaviyo, HubSpot, etc.)
Step 2: DataNostro setup
In DataNostro, create a tenant and import the Container ID. The container deploy runs in parallel on a new subdomain (e.g. track2.store.cz) — with no disruption to Stape.
Fill in the platform configs. Power-ups are bundled (no per-feature paywall like the Stape Custom plan).
Step 3: Parallel DNS
For a week, both hosts run in parallel. In the GTM web container, split traffic 50/50 between track.store.cz (Stape) and track2.store.cz (DataNostro). You watch:
- GA4 reports — do the event counts match?
- Meta Ads Manager — do the Purchase, AddToCart, ViewContent counts match?
- Sklik / Heureka — if you're connecting for the first time, it's pure upside
Step 4: Cutover
After 5–7 days of parallel running, when the data matches across both hosts, you point the track.store.cz CNAME to DataNostro. You turn off the Stape container (it's kept for 30 days in the Stape archive for rollback).
Discount + Care
The migrant code STAPE-MIGRATION-15 gives 15% off for 3 months. DataNostro Care (a paid concierge) does the migration turnkey for CZK 19,900, including a GTM container audit and validation of GA4 / Meta deduplication.
FAQ
What about the Container ID? The Container ID in GTM stays the same. You only change the tracking server URL in the Web GTM container.
Stape Store data — does it come with me? Stape Store has no export. If you have data there, export it manually via the Stape API and import it into the DataNostro Store (endpoint parity).
Will there be a gap in my Ads campaigns? No, the parallel run + deduplication via event_id guarantees 0 ms of downtime.
