Chris Shore has recently published a white paper Porting to Arm 64-bit which you might find useful.
A general point, Armv8-A has two execution states AArch32 and AArch64. Where AArch32 provides backwards compatibility with Armv7-A.
For something like porting it makes a lot of difference whether you mean Armv8-A AArch64 or Armv8-A AArch32.
