  • Hi,

    I understood the pain that you are going thru. But what i can suggest now is if your company is tight on IT budget. You might want to follow the below phases which i often tell my customers.

    1) Switch and firewall standardization. -- This is important, because when there is a support needed for hardware, with a single call to the hardware manufacturer, you will have higher chance in getting your case expedited faster than others. Because of 1 brand.

    e.g if you are on HP Procurve switches, ensure the entire stack is HP stack. You can have mixture of Layer 2 and layer 3 stack. They must be the same brand. Sames goes to firewall. If is a sonicwall then ensure everything in your organization uses sonicwall and nothing else.

    2) IP address allocation table, this is important because since you are taking over and planning for a revamp you should ensure the ip address being iron out on your end before handling the information to the vendor for configuration purposes.

    3) VLAN tagging and network segmentation. This will make sense once your internal network have been recreate.

    4) A Detailed Network Diagram. This will makes your job easier.

     Let me know if you have further questions. I hope it does gives you a vision on what to do next.
