Office Move IT Checklist for Growing Businesses

An office move takes down IT more often than any other kind of business disruption, and almost always for the same reason: internet and phone orders go in too late. Start the IT side of a relocation 8 to 12 weeks before the move date, not the week before, and treat internet activation and phone number porting as the two tasks with the longest lead times on the entire project.

Why office IT moves go wrong

A furniture move is forgiving. Show up a day early, a day late, nobody notices. An IT move is not forgiving in the same way, because internet connections and phone numbers run on someone else's timeline. A new business fiber connection can take two to eight weeks to activate depending on the provider and the building. A dedicated fiber or Ethernet circuit for a larger office can take up to 90 days if new cable has to be run to the building. If that order goes in the week of the move, the new office opens with no internet, which means no email, no cloud apps, and no way to process a card payment.

The other quiet failure point is structured cabling. If a business signs a lease and waits until after the walls go up and the flooring goes in to think about network cabling, retrofitting it afterward typically costs three to five times more than running it during the buildout. Cabling and IT infrastructure need to be part of the fit-out conversation from day one, not an afterthought once the space looks finished.

8 to 12 weeks before the move

• Walk the new space with whoever manages your IT, before the lease is signed if possible. Check power outlet locations, a spot for a network rack or comms closet, and cable pathways.
• Order the new internet connection now. This is the single highest-leverage task on the whole list because it has the longest lead time and the most painful failure mode.
• Start the phone number porting process for VoIP or any main business line. Porting a number to a new service address is not instant, and starting late is the most common reason calls go dead on move day.
• If you run a VoIP system, flag the address change now. Under the FCC's Kari's Law and RAY BAUM'S Act requirements, VoIP systems have to transmit a dispatchable location with every 911 call, which means your provider's registered address has to be updated for the new office before anyone relies on it in an emergency.
• Decide whether to keep any on-site servers or move fully to cloud-hosted infrastructure while you have the excuse to simplify.

4 to 6 weeks before the move

• Take a full inventory of every device that has to move: workstations, monitors, printers, phones, switches, access points, and any cameras or door access hardware.
• Order new hardware if anything is being replaced rather than moved: routers, switches, access points, a UPS for the new comms closet.
• Label every cable and device with where it goes in the new office. This step gets skipped constantly and it's the reason a rebuild that should take an afternoon takes two days instead.
• Run a full backup of servers and critical data while everything is still connected and working.
• Confirm your porting request has a scheduled completion date, not just a submitted status.

1 to 2 weeks before the move

• Confirm the new internet connection is live and tested before moving day, not on it. If it isn't active a week out, that's the point to arrange a temporary backup connection rather than hope it resolves itself.
• Schedule the physical IT move for a weekend or evening to keep downtime out of business hours.
• Set up temporary call forwarding as insurance in case the move runs long.
• Take one more full backup. This is the last one before anything gets disconnected.
• Lower the DNS TTL on anything public-facing (your website, mail routing) to a short interval about a week ahead, so that if your public IP changes with the new connection, the change propagates fast instead of leaving some visitors stuck on the old address for a day.

Moving weekend

• Photograph the rack and cabling layout before disconnecting anything. This alone saves hours during reassembly.
• Shut down servers and network equipment properly, in order, rather than unplugging everything at once.
• Move servers and networking equipment separately from general furniture, ideally in a vehicle where they aren't stacked under anything heavy.
• Reinstall in this order: router and firewall first, then switches and access points, then servers, then workstations and phones.
• Confirm dial tone and test every extension before anyone shows up expecting to make a call.

First week in the new office

• Confirm every workstation can reach shared drives, business applications, and the internet without a workaround.
• Test inbound and outbound calls from the main line and every extension, including after-hours routing.
• Verify ported numbers display correctly on caller ID. This is a common miss and it's the kind of thing clients notice before you do.
• Update your website, Google Business Profile, and email signatures with the new address.
• Walk the space once more with whoever handled the technical side to catch anything that only shows up once people are actually working in the room.

FAQ

How far in advance should we start planning IT for an office move?

Start 8 to 12 weeks out. Internet activation and phone number porting are the two tasks with the longest lead times, and starting late on either one is the most common cause of a rough move-in day.

How long does it take to get internet installed at a new office?

A standard business connection typically takes two to eight weeks to activate. A dedicated fiber or Ethernet circuit that requires new cable to be run to the building can take up to 90 days. Order early and confirm the connection is live before the move, not on it.

Do we need to update anything for 911 calls after we move our VoIP system?

Yes. Under the FCC's Kari's Law and RAY BAUM'S Act rules, VoIP systems must be able to provide a dispatchable location with every 911 call, so the registered service address needs to be updated to the new office before staff start relying on it.

What's the single most common mistake in an office IT move?

Ordering the new internet connection and starting phone number porting too late. Both have lead times measured in weeks, not days, and a late order is the direct cause of most no-internet, no-phones move-in days.

Should cabling be planned before or after the office fit-out?

Before. Structured cabling and network infrastructure should be designed alongside the fit-out, not after. Retrofitting cabling once walls and flooring are finished typically costs three to five times more than installing it during construction.
