Shopware 6 Update from 6.6.8.1 to 6.7.10.2 + German Widerrufsbutton

We are seeking an experienced Shopware 6 developer to update an existing store from version 6.6.8.1 to 6.7.10.2. The update must be handled safely, preferably first on a staging environment, and then deployed to production with minimal downtime. The ideal candidate should have strong experience with Shopware 6 updates, plugin compatibility, theme compatibility, and post-update QA. This is a short-term fixed-price project expected to last less than one month. Important: - We need a fixed-price quote for the full project. Please include your assumptions, what is included, what is excluded, and what information you need from us before confirming the final price. - The project should include the Shopware update, staging/backup handling, plugin and theme compatibility checks, post-update QA, and configuration/activation of the Widerrufsbutton. - Legal note: The technical setup of the Widerrufsbutton is part of this project, but legal texts and final compliance validation should be reviewed by the client or their legal advisor.
