Let’s assume you’ve decided to pursue an Exchange Online migration. Is your move motivated by the 0-day exploits being perpetrated against Exchange servers by HAFNIUM? Perhaps you simply just want to take advantage of all the benefits that moving your mailboxes to the cloud can provide to your organization and your end-users?
Are you looking for a replacement for outlook public folders? Public Folders are unruly, encourage sprawl, are hard to regulate and motivate end-users to circumvent mailbox retention.
Let’s dive into what you shouldn’t be doing while you migrate from public folders:
1. Don’t move everything
Migrate the last 90 days of mail, the next 90 days of meetings with all recurring meetings, all personal contacts, and tasks. Those parameters cover your user’s mailbox content. Migrate the most recently used files and folders by age, keep file versioning to a minimum by only migrating the latest versions and filter out files that are too large or perhaps common file types like media files that tend to be larger.
2. Don’t Forget About Applications
After compiling an inventory of known applications, it is time to begin to evaluate each application to determine its future. Most application migrations to the cloud have little to no ROI. So, you must decide if they are business-critical enough to retain or retire.
3. Don’t Overburden Your Support Staff
The experts overwhelmingly recommended that you schedule migration tasks on the weekdays to begin to push data into the target. Optimally, scheduling during off-peak hours is the best practice to maximize data throughput but we also always recommend that data be migrated continuously, just to a lesser extent.
These are some of the mistakes you should avoid at any cost during migration. We hope that these tips provide valuable guidance of what to do and what to avoid when planning your migration from public folders.
