Changing ISP - DNS MX question

Hi
I am changing ISP and have some questions as I am getting a bit confused, the domain were registered with LCN, but at the time we have a simple reseller plan hosting 10 domains (purely because its cheaper to have a reseller plan than to have 10 separate hosting plans), so the DNS were pointed to HostGator which works well, then last year a websign company wanted to host one of the website abcd.co.uk because their hosting server provided some functions that HG didnt have, so we pointed the A record to them, but rather than pointing it from HG, it were pointed to them directly from LCN, but as its all working well, we left it as is.

Now changing ISP, I am wondering if I should just add the MX record from the master registar LCN as there are options to add MX records, or should I change the IP address from the Hostgator's control panel, personally logic tells me its best to do both the A and MX from LCN as its the highest level, or I could add both the old MX as priority 10 and the new MX as 5 on LCN ?

Apology for long post but hosting/web is not really my area, I have attached a diagram hoping to explain more.
Thanks for any help Old and new layout

Hi,

To confirm, are you trying to change the MX record of abcd.co.uk ? Also please visit the following url and let me know the results to the following questions.

http://www.dnswatch.info/

1. Enter your domain name in DNS Lookup / IP lookup and select the type "NS" and click resolve. Paste the result here.

2. Now enter the domain name in DNS Lookup / IP lookup and select the type "MX" and click resolve. Paste the result here.

Also it would be helpful if you could provide the domain name in question.


Regarding your question,

If the name server for the domain in question is pointing to HG then please change the MX records from the HG control panel. If not you may change from the LCN panel.
