CZ - Sitecore 7 to 8 Migration.

Engaged by CZ for a focused migration project: incorporate their legacy Sitecore 7 Visual Studio solution into a new Sitecore 8 Helix-structured project. The goal was to modernize the codebase to align with Helix principles while preserving all existing functionality.

I cleaned up redundant using statements and resolved circular references, updated NuGet packages to current versions, and restructured the code to match the Helix feature/foundation/project layer architecture. All Sitecore dependencies were updated to target the new version and code was adjusted where API changes required it. The cleaned, restructured code was then integrated into the new Helix solution.
