Our company is planning to merge with another company in the same industry. as i am working in Network administration side what are the points/details i should be asking to other end for a smooth network integration.
Could you please brief me regarding this.
John has some good questions.
With anything you need to understand what you are "getting."
The starting points needed are specific to your role.
From an admin perspective, who will be maintaining it?
Will there be consolidation to one location?
How will everyone be connected?
To migrate you will want some type of VPN solution and run a routing protocol that will be dynamic in nature, eigrp, ospf, etc...
This will help in the advertising of routes and eliminate anything being static that will require manual intervention later.
I went through this at my last company and we did have to do some double nat-ing until we had everything figured out on what we needed to keep and what was migrated then incorporated a new IP scheme by creating a new vlan for the new location and migrating everyone over to it. This allowed us to be geographical in our IP scheme too.
A few questions that I would ask is:
What type of equipment do they have? (firewalls, packetshapers, routers, l2/l3 switches)
Do they run any routing protocols? What type?
Do they have any overlapping addresses with your existing network?
Are there any firewalls in place?
Any wireless access points?
Do they have any remote sites that require VPN tunnels?
Do they have all of the same vendor equipment that you do, i.e., all Cisco equipment, and is it all compatible with what you have. (You may have a router from a different vendor that only supports RIP or OSPF, but you run strictly EIGRP on your network (Cisco proprietary.)
What type of outside-in access does this company have to support for servers like AS400, Web, Mail, etc.
What does their daily traffic flow look like? Are they maxed out on their bandwidth?
Answering these questions can sometimes cause more questions, but this is a good start.
