Currently, does it take some hours to transfer sending from one wallet to another?
I used the command,
sendtoaddress CredaCash_b................... 10000numbers of time to empty one wallet for consolidate to another wallet, but now after a day still not seeing input of transactions amount in the other wallet.
So is this an issue or I did something wrong here, please help!

Try using the poll.cc command on the sending wallet and wait a bit. Also, use the --reset-wallet command line option on the sending wallet. Try resending with 5k or 10k, then work up to 100k. That worked for me.
