One thing that was not clarified for you.

You can not just arbitrarily change the useful life of an asset. The examples you provided are perfectly legal too. You need to continue depreciation on them using the same MACRS depreciation schedule they were started with. Just use the guidance provided by AnnettB to enter them so you continue depreciating them the same as you have been in the past.
