What will happen if you change the site engine, delete all pages and file a new site on this domain?

Question

Google

Hi all! There was a question...
There is a site with tits10 and attendance of 30 uniques a day. There was a need to change the site engine to another one. It is not possible to save the content of the site (i.e. there are 500 posts on this site and there is no time and effort to manually transfer sweats to a new engine with identical url addresses). more or less beautiful and readable.
After I change the engine and start filling the site with new articles, how will the search engines react to this? Will they send my domain to the bath?

Answer 1

They won't send you to the bath. All positions will drop. New ones will come in a year. But for a long time the search engines will remember that "such and such a resource was not found." 500 posts is not much. I have to transfer 30,000 posts now, wow

Answer 2

there are 500 posts on this site and there is no time and effort to manually transfer sweats to a new engine with identical url addresses

why do it manually?
They will react like a new site. TIC is likely to be lost.

Answer 3

Write a script that transfers articles to a new database. Although messing around with this at 30 uniques is most likely just for sporting interest.

Answer 4

It is highly desirable that the URLs be saved.
Set up redirects (rewrite in terms of Apache)
