Migrating to new core switches

I am intending to buy two new Cisco Catalyst 4513 switches to replace the current core switches (4000 series), which Layer 3 routing is enabled. However, I am not sure as to how to perform this so can someone please put in the steps that I need to perform in order to:

- Minimize downtime
- Migrating VLANs
- Migrating the routing process
- Spanning Tree
- Etc. Etc. Any other important items?

I'm sure I had left out several other things, but what are the things that I should look out for? Thanks in advance, everyone.

Dear  follow the following steps for the sucessful replacement of the new core switch

1) Document the current network layout
2) Label all the connections (GBIC modules in old core switch)
3) Back up the current configuration
4) Configure the new switch with an IP address, enable name, vty, routing protocol, VTP domain, stp parameters, vlans details.
5) Make sure current power can support the new switch.
6) Keep all your tools ready next to the communication cabinet.
7) If some thing goes wrong be prepared for the backup plan ( i hope nothing goes wrong)
8)Check the new modules in the core swicth , make sure exsisting fiber patch cords can be used with the new module (GBICsSPF or LC or SC).

If i remember i will post you.

Cheers

Thanks yasirirfan for the reply but it may be too generic. As mentioned in my question, I would like to know more about configuration of the switches, as in how to migrate the configuration from one switch to another while minimizing downtime. Basically, can you or someone elaborate in more details for point 4. I would like to configure as much as possible before the migration day, during when all I need to do is just to plug the cables over to the new ones.

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

For the point 4

Here are the details

1) Configure Hostname
2)  have a management vlan then shut down vlan 1.
3) Create a VTP domain
4) Make it as a server
5)configure all the current vlans
6) Configure the routing protocol if ur using for intervlan communication.
7) Configure STP and its parameter.
8) Configure console & VTY passwords
9) configure enable password
10) Configure username and password
11) Enable all the interfaces which ur planning to use.

If you need further info do let me know.

Cheers

Once u fixed the switch in cabinet and powered on then remove the old connections and insert them into to the new switch

Create a test enviroment with the switch and a couple pcs.  Do all configurations and then test in test enviroment.  Once testing complete start to roll out switch.  I would try to integrate the new core switch with the old one that way you can migrate connections without taking everyone down at once.
