Which protocol are you using and which one do you want to change to? Also please provide the configuration for the routing protocol you want to change if you want further assistance.
Simple routing protocol configuration is easy to migrate
e.g. if you have EIGRP and you want to change to OSPF:
Before:
router eigrp 100
network x.x.x.x x.x.x.x
After
router ospf 1
network x.x.x.x x.x.x.x area Y
Likewise with RIP too

Bilai,
Your example would result in changing the routing protocol - however it wouldn't provide a way to validate your new routing protocol before allowing it in production.
Running a dual routing protocol and manipulating the admin distance for protocol migration is less intrusive way and provides againist config mistakes and an easy way to backout your changes if required without losing connection.
The down side would be memory/cpu utiliastion of the router/switch

Hello Paul, I fully know this and this is why I had asked and queried about it to gain more of an understanding of the current topology.
There's not a mention of a production environment and just to re-iterate that it was just basic bare bone config. (I know there's a lot more to it)
As an example yourself and I have provided what it would look like in the configuration, this is the most we can suggest without any further information.
And if any changes were to be made in a production environment, they should be made out of hours for sure :-)

Hello
For igp's
eg.
from rip to eigrp
router rip
network x.x.x
router eigrp
distance eigrp 121 170
network xxxx
when you ready just remove the distance command the eigrp routes will take precedence
or
router rip
distance 89
network x.x.x
router eigrp
network xxxx
