If I'm change HTTP to HTTPS , Is it effect my SEO ?

Hey there,

you can request a recrawl from GSC. If you implement it correctly and avoid some of the headaches a screw up will cause:

Here are a couple guides that should help you.

Regarding the backlinks, it will just take some time for them to be recrawled and accounted for in your new url. I would say make sure to create two GSC accounts not to lose the history.

Thanks,
