Our seven-step migration process

Our planning workshop is essential to agree scope, timescales and costs.

Once the project starts, here’s what to expect:

We begin by establishing your Microsoft 365 tenant, integrating your company domains and setting up accounts for all staff members. This initial setup is crucial for aligning your organisational structure within the Microsoft 365 environment, ensuring that all user accounts are configured and ready for seamless integration.

Our team expertly handles the migration of your critical data, including migrating mailboxes, email addresses, calendars, contacts, tasks, and any other data specified in our agreement. We use proven migration tools and strategies to ensure that all your data is transferred securely without loss or corruption.

Before going live, we conduct thorough testing of the new Microsoft 365 setup to ensure everything is working as expected. This includes verifying that all data has been accurately migrated and that all features and functionalities are operational. Testing helps prevent any potential issues that could affect business continuity.

On the agreed switch-over date, we finalise the migration by making the necessary DNS changes to point your domains to the new Microsoft 365 services. This cutover is carefully planned to occur during off-peak hours to minimise any disruption to your business operations.

We provide comprehensive training for your IT staff or designated team members who will be administering the Microsoft 365 environment. This training covers all aspects of management and maintenance to ensure they are well-equipped to handle the new system.

To maximise the benefits of your new Microsoft 365 capabilities, we offer optional training sessions for your team. These sessions are designed to help your team understand and utilise the new tools and features effectively, enhancing productivity and collaboration within your company.

After the migration, our commitment to your success continues. We offer ongoing support and are available whenever you need assistance. Whether it’s a minor query or a need for troubleshooting, our team is ready to help ensure your Microsoft 365 environment runs smoothly.

What our customers say

“We had one of the Compete366 engineers work with us on the project. He was exceptional and even assisted on some issues caused by the migration which were outside of the 365 domain. Running Office 365 and Sharepoint via an Azure domain gives us a high level of control including user access and data sharing without needing an in-house server to maintain. It allows me to administer access or revoke access to our data. It has been hugely beneficial with everyone being able to access data and synchronise from anywhere at any time.”

Ed Birks, Managing Director, Langstaff Ellis

“Compete366 pointed out challenges we didn’t know we had. They understood our space.

“This project was one of the smoothest we have run. There were no problems at all with email availability, then switchover was seamless. On the day of go-live and even the week after, we heard virtually nothing from our end users, which was a very good sign. Their Office 365 accounts and email were working exactly as they should. When it comes to email migration we know that no news is often good news.”

Paul Tarling, VP Customer Success, UK & North America at Datix

Paul Coyne, Rusada

“We had great support from the Compete366 AVD expert, who was really helpful, and guided me through options to tackle issues that arose.”

“The great thing about our AVD set up is that we have a custom set up for each project which Compete366 showed me how to do. And with the scalability and flexibility of AVD – we can meet clients’ expectations and get project users up and running more quickly.”

Amir Dangol, Senior IT Manager, Integrity

“We were immediately impressed with the advice that the Compete366 specialists in Azure Architecture were able to provide. This was all new to us and we really needed some external expertise that we could use to get our questions answered. The beauty of working with Compete366 is that we transferred our Azure consumption to them, and at the same time received all of their advice and guidance free of charge.”

Tim Entwistle, Head of Software Development, Herrco

“Working with Compete366 has been like extending our own team – they are extremely and easy to work with. Right from the outset, it was clear what was on offer – everything was presented to us in a straightforward and uncomplicated way. They also provided just the right level of challenge to our developers and saved us time and money by suggesting better ways to implement our infrastructure.”

Oliver Mackereth, Project Director, Hanse

“Compete366 were able to help us leverage some useful contacts in Microsoft. We really value the expert advice and guidance that they have offered us in setting up a highly scalable infrastructure. We are also setting in place a regular monthly meeting which will allow us to further refine our architecture and ensure we keep on track as our requirements grow and change.”

Matt Brocklehurst, Technical Director - AWOL Adventure

“I have been delighted with the migration, where my team worked very hard, supported by expert advice from Compete366, and achieved everything in the timescale we had set out. Compete 366 made sure that we didn’t make any expensive mistakes, and guided us through the process”
