Updating a Tree on Ancestry for DNA Purposes Only - Advice Needed

[Elderflower]

I have a tree that I uploaded to Ancestry nearly three years ago for DNA matches only. The tree is private and not kept up to date via Ancestry. My "proper" tree is on my laptop where I use different software to store it and update it regularly. I now have lots more detail, and people, on my "proper" tree and have undertaken much work using DNA matches etc to find this information.

Does anyone know what would happen to all the DNA matches, groups and comments I have noted against my matches if I delete the original tree and upload an updated version? I would give the new tree on Ancestry the same name as the original one. Would I lose all the information I have noted on my list matches and groups?

Has anyone else done this?

Any advice is appreciated.
