Theme migration for agencies
Move client redesigns from approval to production without a big-bang launch.
Preview a redesigned route against the client’s real content, launch only what is approved, and keep every unrelated page on the current theme.
Private theme preview
Route-level release scope
Pause and fallback controls

Client launches fail when every decision converges on one day.
Traditional agency launch
- Stakeholders review a staging approximation
- The entire redesign ships in one release
- Every template and integration changes together
- Rollback means reversing the whole launch
ThemeRouter agency workflow
- Authorized stakeholders review a private route preview
- Only the ready section receives the assigned theme
- Unmatched sections remain on the active theme
- Pause the assignment to return that route to fallback
Agency rollout plan
A review process that continues cleanly into production.
Use the same route definition from internal QA through client sign-off and measured release.
1
Choose an approval route
Start with a contained page family such as Case Studies or Landing Pages.
2
Preview privately
Authorized reviewers validate the installed theme with current copy, media, forms, and integrations.
3
Enable the approved scope
Enable the assignment only after the client and delivery team complete their own acceptance checks.
4
Report and expand
Use the client’s existing measurement systems, then repeat the workflow for the next ready section.
Recommended first route
Start where feedback is valuable and rollback is simple.
Editorial sections create enough real-world evidence without putting the entire client site at risk.
/case-studies/*High content value, moderate operational risk
Start here
/landing/*Campaign-specific approval and measurement
Next
Everything elseStable experience while approvals continue
Current theme
What to validate before adding the next route
Visual acceptance
Layouts, content variants, forms, and responsive states match the approved design.
Experience metrics
Performance, engagement, and conversion signals remain within agreed thresholds.
Stakeholder confidence
The client understands what changed, what stayed stable, and how rollback works.
Agency workflow questions
Yes. Use preview mode to review the redesigned route against live content before activating it for visitors.
Disable that route to return its traffic to the current theme while the rest of the approved rollout stays unchanged.
No. Both themes render content from the same WordPress installation and database.
