I try to migrate CA 2008R2 from CSP to KSP but I have some difficulties...
1) migrate CSP to KSP on my 2008r2 server
2) Migration SHA1 -> SHA 2
3) Migrate to 2019 server
1) I can't migrate without 2012+ help server. I need to export the key , import it on 2012 to migrate from CSP to KSP and then export it again to import it on my 2008r2 with new KSP provider.
2) When I try to backup my 2008r2 CA with KSP provider, it doesn't work because key can't be exported. I don't understand why. I used Microsoft documentation for it.
Maybe my migration order is wrong and I need :
1) Migrate to 2019 server
2) migrate CSP to KSP on my 2008r2 server
3) Migration SHA1 -> SHA 2
Thanks for your help.
