An office move without any disruption is possible but it’s the planning that will need to take place prior which will make the biggest difference in achieving a seamless move. Unfortunately there is no set formula and every move is different. The good thing is the fundamental elements stay the same. Let’s start by answering some initial questions:
There are some variables to take into account for and unfortunately it really boils down to what you want to spend. The best option for any relocation to is to have the premises or new site ready for business with a working model in place. This means that you would have all of your comms room and infrastructure in place ready and tested. This will be expensive but allow for a smoother transition. Imagine your new premises to be almost like a second site that could be used as fail over or a space that could be used in a Business continuity model, for e.g. if your current site suddenly has a critical failure this fail over site would be the site that staff would relocate to continue working from. This is the ideal scenario but rarely can be achieved as old systems are in use and cannot be simply replaced or there is fund restrictions which prohibit some of this.
What elements to plan (in particular with regard to internet/network & telecoms)
This is related directly to change management process, and how you will be setting up your new premises or site;
If you are transitioning all of your IT infrastructure to new equipment is there going to be a transfer of information or will it needed to be tested prior to either moving or switching off, this can be coordinated with your current IT Infrastructure team they will have more details on the transfer or requirements. If you are relocating existing equipment, you will need to check of any operational issues with a shutdown or preparations that will be required. This includes how this will effect staff or systems that rely on the infrastructure and how this will be affected. This will take time and preparations and may require notifying other teams, business units or staff this relocation or shutdown effects and approvals may be required from those affected.
This is difficult to answer without knowing all of the variables. I generally start my planning process with the thought how long will it take to prepare the move and the required people/equipment and services. You are sometimes reliant on outside organisations out of your control like Electricity or carrier providers. You may need to procure new infrastructure and equipment for the new site and there may be lead times associated with this, all of these things will assist in your timeline of planning.
