I wouldn't delete the old posts, especially if you still have relevant material in them. You might need to update with newer or expounded information and then re-index with Google, but salvage what you can.

I spruced up my old posts and resubmitted when I relaunched my website. The old content is getting traffic and the updated graphics and content is working well.

Hope this helps. Wishing you a successful journey!

Glad that you are back! Edit the posts if you wish, but don't delete it!

Welcome back! Keep your posts, don’t delete content you e already worked one. Like others have said, update it and then start adding some new stuff.

I would suggest to you that you update your previous posts.
You can do this

I too am restarting my recruiter site after quite some time. I wish you the best. Hope I can be of some help down the road.

Ever Forward,

Hi Gordon, I would keep your posts and update them, add content, update old content etc...and then start adding fresh content as soon as possible.

Hi, Gordon.
Welcome back to continue your work.
It is entirely up to you what you want to do with your site.
Only you know the best.
Whatever it is, I wish you all the best.

If it were me, I would edit your posts and resubmit them.

Watch out for SEO in transition and what about the effectiveness of URL and continuity of hosting fees
