0% credit card to pay off overdraft

You mean you've done a Money Transfer (MT) to pay off your overdraft and now you are paying off the card at £200 pm. Did you have to pay a fee to get the Money Transfer and how much did your overdraft cost you each month in charges?

I ask these questions because some people will have fee-free overdrafts and, rather than incurring a possible MT fee and shifting the debt to a product that will require a payment every month, they might simply choose to spend, say, £200 less every month from their bank account and reduce the overdraft at their own pace. I accept that requires discipline and care to achieve.

Obviously, where someone has an overdraft subject to charges, the ongoing nature of those charges could quite quickly exceed any MT fee and the use of the MT to instantly switch the full overdraft to an interest-free product then makes perfect sense. Obviously this requires discipline too, but you have no choice with this option, as the MT card will require a payment every month regardless of your circumstances.

Whatever your circumstances, and whatever method you choose, you still have to eradicate a debt and that won't always be easy. It is therefore important to understand exactly what created that debt in the first place and ensure that doesn't happen again.

The worst thing would be for a person in this situation to end up dipping back into their overdraft simply to meet the monthly MT card payments.

Yes, I would agree that avoiding those monthly overdraft fees is good and that will free up an extra £80/£90 to enable faster clearance of the debt itself.

As for retaining the overdraft facility, you will get a lot of opinions as to whether you should or shouldn't. The question is, how disciplined are you now that you've taken this step towards freedom from your overdraft debt? Only you can answer that, but if you are at all worried about sliding back into the overdraft, then it may be just as well to get rid of it.

Your challenge now is to keep up the £200 monthly repayments to the credit card. Prior to this, you were only having to find £80/£90 per month to cover the overdraft fees, but now you are having to find a full £200 per month to manage the credit card.

You haven't said how big the debt is, or what the mandatory minimum monthly card payments are going to be but I imagine they must be less than £200. If so, that gives you the scope to reduce your card payments during 'lean' months, but I would hope that won't be necessary.

As long as you have understood why you were in your overdraft and are confident that you can manage the £200 monthly commitment without getting into trouble, you should be OK. At the end of the day, clearing a debt is all about finding the money to do it - yes, reducing the cost of the debt is good, but you still have to understand that you were in debt for a reason, and identifying and resolving that will be necessary to avoid slipping back.
