Can a core wallet coinbase-transaction (generation transaction) be moved intact to a net new core wallet? Can a core wallet coinbase-transaction (generation transaction) be moved intact to a net new core wallet?

Wanting to go through cautious steps to claim BCH but, I hear a BTC coinbase-transaction when still 'whole' can be worth more when sold 'whole' than the sum of the BTC in said coinbase-transaction if divided up. 

In v0.14.2 bitcoin core wallet, is there a way to move a coinbase-transaction intact/whole to a net new core wallet (so it remains worth more as noted above)? Source wallet does also contain some fractional BTC that can be used for fee.
No. Any transaction that you make will make it "not whole". i.e. the "coins" move to a different output. You cannot move any coins without making a transaction.
