what happens when organizations in the middle of transformation initiatives — or who haven’t even begun yet — are suddenly faced with mandates to migrate to the cloud?
The 2020 COVID-19 pandemic turned out to be a test case for the ability to accomplish cloud migrations on tightly compressed schedules. While some scheduled migrations were pushed back, others were suddenly placed on the front burner. Notably, state and local governments which had been among the slowest to adopt the cloud were now faced with work-from-home mandates while still expected to deliver key public services. IT departments, already dealing with disrupted operations, were pressured to implement work-from-home arrangements and needed to be in the cloud immediately. Files in on-premises network drives and other assets located behind the firewall needed to be made accessible. Telephone systems needed to be reconfigured to forward calls.
A call to arms — and managed service providers
Organizations needing to cloudify in short order turned to trusted managed service providers with the specialized knowledge to handle migrating key applications and workloads to the cloud. What many discovered is that thanks to online tools, the essential infrastructure to enable a secure remote work plan could be in place, migrated to the cloud on a compressed timeline, and without compromising continuity of services. Part of this success was due to the prevalence of office suites, with their multiple tools for productivity, shared file storage and collaboration.
Lessons learned from experience
The experience gained applies to any IT organization or MSP needing to pull off a critical migration in short order. One challenge to take into account is the demand placed on the cloud infrastructure. During the pandemic, with so many organizations doing remote work, the immense scalability of the cloud came to the test, and for the most part it shined. However, especially as use of online file stores such as SharePoint Online and OneDrive skyrocketed, Microsoft and Google throttled traffic, especially during peak business hours and some migrations ran into capacity issues and took longer than expected.
Since the tools are themselves in the cloud, in many instances the entire migration task could be performed without an onsite visit — a key advantage given stay-at-home mandates. If the IP addresses (or URLs) and administrative credentials are known, the entire process can complete remotely. Migrating an entire workforce to the cloud for basic collaboration, using email and applications such as Teams or Skype, can be accomplished in anywhere from 24 hours to a long weekend. With careful pre-planning and consideration to details, organizations are able to shift to remote work without missing a beat. The details include:
- Migrating emails first to keep the lines of communication open
- Using date ranges to migrate the most-essential emails selectively
- Paying careful attention to data volume during the migration to avoid overusing bandwith, which could trigger throttling by Microsoft or Google
Provided the number of users, size of the mailboxes and total volume of data are not overly large, an organization can be ready for remote working with a new cloud instance in a long weekend. The rest of the migration can follow in the days after, backfilling the email boxes with the balance of the emails. Migration of less-essential files in online stores can take advantage of off-peak hours and weekends when throttling is less of an issue.
Mission accomplished — with more to come
The good news is, once the migration is complete, organizations are in a much better position to effect digital transformation for other key processes, and position themselves for the long term future of remote work
