Upcoming01
Deadline pressure is real.
Sentinel stays narrow: HubSpot platform migrations, deadline-ranked evidence, and customer-safe reports for teams that need to plan the work before the cutoff.
DeadlineWhat is changingWhy it matters
Projects v2025.1 deprecation
Builds and deploys on v2025.1 stop after the sunset date.
Legacy CRM Cards sunset
Existing legacy CRM cards need migration to App Cards before sunset.
02
Evidence packs your team can act on.
The planned output is not a migration button. It is a structured artifact that lets RevOps, agency leads, and engineering owners see what needs review, why it matters, and where the supporting HubSpot source lives.
Dashboard
Interactive view of deadlines, backlog items, and compatibility signals.
JSON
Structured evidence export for migration planning and internal systems.
Stakeholder-ready summary with findings, limitations, and source citations.
Citations
Links back to HubSpot primary documentation for every forcing function.
03
Read-only by design.
Sentinel protects customer portals by staying out of the mutation path. It reports the migration work and cites the source. The customer or their agency performs the change.
No write scopes
Read-only HubSpot access only. No portal mutations.
No auto-migration
Sentinel reports the work; it does not change customer portals.
No attestations
Engineering evidence only, not legal or compliance certification.
No consulting hours
Product workflow and reports, not manual services.
