Update apk when previous certificate will expire before 2033

I've to upgrade an android app on the market.

I try to sign with app with my previous certificate (Certificate expires on Thu Oct 08 10:22:43 CEST 2020.) and the market return the following error:

"Market requires that the certificate used to sign the apk be valid until at least October 22, 2033. Create a new certificate."

If I try whit a new certificate the market says

"The apk must be signed with the same certificates as the previous version"

What's the solution for that?

What will appe开发者_JAVA技巧nd in 2020 if Google will change the limit to 2043? Nobody can update this app?

Unfortunately, you can't, unless you change the package name.
