Hello Zee,
could you please provide additional information on what you would like to do?
If you plan to transfer your domain, there is no need to edit any DNS records, which would instead be used if you plan to set up a redirection.
Here are the two alternatives:

HI Eric. It appears the MX DNS does not like/accept the "10 mail.vetscallcenter.com" as directed on the W5 Hosting Domain configuration panel.   My curret Host/Registrar is Netfirms.  Screen follows. Thanks.

Eric, Thanks for your assitance. I am looking to redirect to W5 Hosting. (I do not see the transfer option)

Here are the DNS setting from my current Netfirms hosting provider:

Hello Zee,
you can initiate a transfer by choosing Buy domain on one of your active hosting spaces.
When you specify your domain, it will be detected as already taken and you will have the option to transfer it.

If you need to use the redirection through DNS for any specific circumstance, the 10 should be the priority for that record.

Thank you Eric. I will specify 10 priority. 

In my screenshot above, how about the NS and SOA settings? They still point to my current hosting registr. Is this correct?

Hello Zee,
it should not be necessary, I will update you if the process encounters any issues.
