Merging 2 assets

Suggested

I have a situation where two assets were setup in SAGE that should be combined into 1. Both have depreciation run on them.  What is the best way to combine the 2 assets without affecting the integrity of the depreciation that has already happened? 

I don't want to have to undo and redo the existing depreciation on both. 

Any suggestions would be greatly appreciated as I would like to get this done prior to year end. 

thanks!
