DKIM key rotation 1024 -> 2048

[mdrabble]

We use Office 365 and the current DKIM records are using 1024 keys - how difficult is it to rotate the key to 2048 versions and are there any gotcha's I need to be aware of?

 

Is it a case of rotating the keys and then updating DNS?

 

Cheers

Bascially this (should be link here.....) , shouldn't need to touch DNS.

 

Didn't have any problems occur.

Guidance available here, but as above no need to do anything with DNS.

Thank you so much :-) very much appreciated.

 

I would have done both at the same time, so good job i asked :-)
