User story

"As a client/partner developer I want to use Spartacus 6.2 in my web application together with Bloomreach Content SaaS and Merchandising functionality"

Technical description

Upgrade to Spartacus 6.2 using the upgrade steps documented here. There are some additional upgrade tips mentioned in the feature document.

QA

The end result should be an upgrade Spartacus integration library and application that is still fully working and works with the Content and Merchandising products.

You can verify this by creating a new Channel using the Spartacus template and check if functionality works as expected.

There should be a green build result in Github that ran some smoke tests before the code was merged back to the 'main' branch.

There should be a new major release of the @bloomreach/brx-spartacus-integration library on NPM.
