There is no one-size-fits-all answer to this question, as the answer will depend on the specific blog and its content. However, in general, it is possible to archive a WordPress blog IF the blog’s content is consistently updated and there is no need for the blog’s current content to be accessible to readers.
If your blog’s content is updated sporadically or if you need to keep some of the older posts accessible for historical reasons, archiving the blog may not be the best option. Additionally, if your blog has a lot of affiliate links or advertising, it may not be feasible to archive all of the posts.
In these cases, it may be more practical to simply remove old posts and create a new blog from scratch.
Ultimately, whether or not you can archive a WordPress blog will depend on a variety of factors, including the nature of your blog’s content and how regularly it is updated. If you are unsure whether or not archiving your blog is feasible, please contact an archiving specialist for more advice.
