1. Activate TS1.5

Go to Backoff.
Open Internet theme → General structure → Graphical theme.
Choose “Evolution”.

2. Test plan after activation

Follow the OLA Service Hub guideline:

2.1 Functional test

Run a full purchase flow:
Home page → Product → Calendar/Timeslot → Seat map → Cart → Checkout → Payment → Confirmation.
Make sure the buying process works fine.

2.2 UI/UX test

Check light customization setup:
- Background, header, footer colors.
- Text and label colors.
- Labels from Backoffice show correctly.

Check disabled buttons, warning messages, and step bar colors.

2.3 Cross-browser test

Test on Chrome, Firefox, Safari, Edge.
Test both desktop and mobile (responsive).

2.4 Regression test

Check that default functions are not broken (example: modify seats for normal events, add product link).
Test multi-language if supported.

2.5 Validation before go-live

Run at least 1 Ticketshop in Preprod before applying to all shops.
Migration to Production only if checklist = 100% pass.

3. Special test for Ticketshops with existing customizations

3.1 Review custom code

Download the zip with custom.css and custom.js.
List all existing custom work (hide/show buttons, popup, style, flow changes).

3.2 Collect customer cases

Get list of Ticketshops with custom work from past Service Cases.
Contact customer to confirm which custom to keep or remove.

3.3 Decide before migration

Remove/disable unused custom.
Keep only confirmed ones and mark them for test.

3.4 Backward compatibility test

Check that old custom is still working in TS.15.
Run full checkout with custom active.
Verify documents and email templates keep the custom.

3.5 Customer sign-off

Share test results with customer.
Ask for confirmation that all required custom works fine.
