CA server migration

Hello samsung,

According to:

See the part about 32bit to 64bit in the above one:
"Moving Certificate Services from a 32-bit operating system to a 64-bit operating
system or vice-versa may fail with one of the following error messages:
The expected data does not exist in this directory.
Restore of incremental image cannot be performed before performing restore
from a full image 0x8007010b (WIN32/HTTP:267)

Database format changes from the 32-bit version to the 64-bit version cause
incompatibilities, and the restore is blocked. This is similar to the move
from Windows 2000 to the Windows Server 2003 CA. However, there is no upgrade
path from a 32-bit version of Windows Server 2003 to a 64-bit version. Therefore,
you cannot move an existing 32-bit database to a 64-bit database."

it is not possible that way.

Additional i will crosspost this to:

The better place for CA questions.

Please note that the article referenced by Meinholf refers only to migrating
a CA from x86 to x64 Windows 2003.

The Active Directory Certificate Services Upgrade and Migration Guide
( (WS.10).aspx) states that
migration from x86 2003 to x64 is a supported migration scenario.
