You should have two depreciation schedules, one with a placed-in-service date in 2019 and the other (relinquished property) with the original placed-in-service date where depreciation is continuing according to your original schedule. If you opted out of the foregoing, then there is only one asset, the replacement property, that is being depreciated.
