Will your IP addressing and naming standards going to be the same? If not, you may have a whole West Texas sized can off whoop waiting to go off underneath you if some programmer hard coded an IP address into an application...

I'd have the DR plan available, in the event of an unplanned outage. Then you would have a reference point for beginning recovery operations.

Make sure of all power, network drops, connectivity, etc before planning on moving servers. It never ceases to suprise me the number of bad network drops you can discover in a brand new facility. Plan to have your wiring crew standing by.

Best of luck on your move.

First, try to identify any shortcomings in your existing setup. All those times you said "I wish blah blah". Don't just repeat the same mistakes.

Have the new network baselined before you get on it. This will help later if you think you are having an issue.

Make sure your server rooms are on their own circuit.
Make sure your server room is cooled.
Make sure your server room is NOT CARPETED.

Decide where SOMEDAY SOMEONE MAY setup a computer or networked printer. Double what you think you NEED now for network. Cable is cheap, having to rerun new lines one at a time isn't.
Also, if you have or are thinking of IP PHONES, this will DOUBLE your network over night.

Replace any hubs with switches.

Get a good map of the network, and lable your patch pannel.

Pick the best office first!

In general -- and this means in life, not just in IT -- moves go the most smoothly when you concentrate on the move and are not trying to also make some other change at the same time. It's a time of high emotional stress, there are lots of things that can go wrong, people are not at their best, and you're not as big an expert about the new place as you were about the one you left.

If you want to change something else at the same time, think long and hard about it before jumping in. You don't want to be remembered as the guy who screwed up the move by trying to be clever. If anything goes wrong, even if it has nothing to do with you, you will be blamed for it if you tried to add something additional.

We are also in the process of relocating office. The company is about the same size as well!

There are a lot of things to consider, and it is best to start at the beginning and go through them. We have the unfortunate situation where we havea time constraint on use to move very quickly so some things are not going as well as we would like.
Anyway since it is an office move can I assume you have someone organsing the lease on new premises? If so then they should form a committee - say that person, the office manager, yourself for IT and comms, and possibly someone on the accountancy side. Why? Well it is like this:
1. The person arranging the new premises will understand what furnishings and fittings are already there and what will be moved or added. Also what needs to be done in the premises you are vacating. You all need to know that for your respective areas. This will help you for wiring, computer room ventilation and power supply, etc.
The Office person will needs to coordinate advising clients and suppliers of the change of address, phone, mail, couriers, as well as order new stationary supplies.
IT will need to know if the new premises need wiring, what is there, what the computer room is, and airconditioning there.
A legal expert should ensure any new leases are really any good, as well as ensuring vacated premises do not cost to rehabilitate to the landlords satisfaction.
Together you can also look, with an architect, at existing equipment and how it will best fit into the new premises. This is not a trivial task.

IT will need to consider timing of swinging existing data and telephone circuits over to the new premises, who your suppliers are to do this, who to call in case anything breaks in transit, when to shut down servers, who the carrier will be, backups to make prior to the move, floor loads in the new premises for rack space, Internet and external data connection providers and users will need advising when the move will be made, DNS and web entries externally may need to be changed (check out anyway), and any arrangements for overtime.

All this has to tie into who who the removal company will be and what they will move and how so ensure the committee checks them out thoroughly.
If the new premises need decoration prior to moving in then sufficient time will be required for that so there are implications on the relocation date. Colors for walls, carpets, curtains, etc may need to be picked out, so ensure your architect helps in this, but do not trust them to make the decisions.
Telephones can be tricky, especially if you have to change provider (which we are doing) so check this out early. A simple change in area code can present all sorts of complications but if they can forward your old location to the new one for a period it may give you some grace period to advise everyone.

Above all act early on everything and do nothing in isolation to others in the company. Keep the other staff aware with weekly updates on progress, and sort out the floor plan and new staff locations early. There will be competition for space and privacy if they can get away with it so ensure you have CEO support for any plans your committee comes up with.

Record and document ever meeting and keep all emails. After it is done you can discard them, but until then it pays to have a record so that decisions are kept to.

Finally book a holiday a week or two after the relocation date for yourself - you are going to need to relax for a week to unwind the stress.

Good luck. I can let you know how we get on or more detail if you wish to contact me direct.

Thanks to all of you for your advice on this. I am already adjusting my plan and making sure I get to see the space before we sign a new lease (if we sign a new lease).

Thanks a bunch.
