Does oracle fixed asset calculate depreciation reserve at the point of upload or retirement of NBV

We moved from JDE to Fusion in 2019 and took on asset books. For Asset 1 we loaded what we had in JDE for Accumulated Depreciation of (as an example) GBP100 using JDE’s STL method of Depreciation for 4 years.

On Fusion, Asset 1 had a Depreciation Reserve loaded of GBP100 with the same in-service date as JDE also using STL of 4 years.

Does Fusion adjust that GBP100 to what it would have expected that balance to be at that point of upload, or is that where it calculates NBV Retired amount at the date of retirement?
