should i use the class sync chrome extension when updating an old project to relume style guide client-first v2.1?

The community member is updating an old project to Relume Style Guide Client-First v2.1, and they have a question about whether to use the Chrome extension "Class Sync" on or off. They also mention that they should delete the old Style Guide, clone the new style guide project, select the Style Guide page, and then select and copy the page-wrapper.
