The migration of emails and files was carried out over a weekend to reduce the downtime, first, we migrated all the email accounts and checked there were no errors. After the emails had migrated, we let the management and out-of-hours team know their new credentials and assisted with setting up the emails.
Then we moved all the files from Dropbox to SharePoint and applied for security permissions as per the documentation provided by the Operations manager. After the files where migrated, we changed Dropbox to read-only.
Field engineers were then on site for 8am at their head office in Maidstone to assist other office staff. Copper Jax has been on Microsoft 365 for over a year now and their productivity has increased due to minimal issues.
