Reclass old item to new item

Hi Experts,

let say I have an item "item 001" that has many lot no. ( can be "1","2","3", and so forth )

1. is there any ways that I can do transfer or reclass to new item " item 002" with NO lot No settings
2. is there any way I can do transfer or reclass to new item with fixed lot no on new item ( for example "a")

thanks all
