You don’t actually copy the data to a BCV manually. Here is the command:
convert meta SymDevName config=MetaOption
[, stripe_size=MetaStripeSize>[cyl]],
[, protect_data=[TRUE|FALSE],
;
So you need to create a BCV which is of same configuration as the current meta and specify it in the command. On issuing the command a clone session is created to protect the data.
Note that if you are using a thin BCV, the BCV should be persistently allocated and preallocated for this to work

Why do you want to go from striped to concatenated?

Converting from concat to striped is similar to expanding a striped meta. You can use a bcv meta to protect the data. Command syntax available in the array controls guide
But If you want to convert from striped to concat…Technically it will work but its guaranteed data loss. It is never advised to do this.
