Many organizations are moving their Exchange email systems from on premise to the cloud via Office 365 to save cost, simplify operations, and increase ease of use and productivity for their employees. Migrating the contents of an on premise Exchange email system to Office 365 is straight forward and can be accomplished in a relatively short amount of time. But what if your organization also has an on premise legacy email archiving system as well?
The fact is, migrating a legacy email archive to Office 365 is not as straight forward as migrating the “live” mailboxes from an Exchange system. This is due to several factors including:
Once comfortable that the email archive migration can be accomplished successfully without increasing risk factors, the main question remains; does it make financial sense to actually migrate your email archive to Office 365 or leave it where it is? Considerations include:
The above are just a few of the numerous variables that could be taken into consideration when building an ROI model. However, in many cases we can look at just a few email archive cost variables to see if migrating your legacy email archive to Office 365 makes financial sense. One last point to keep in mind in analyzing a financial justification; the Office 365 personal email archive folder for each mailbox is free…
Based on the basic fact that the only real cost of moving your existing email archive to Office 365 is the migration itself and the fact that once in Office 365, there is no ongoing costs for the archived data, the actual ROI is calculated from the cost of the actual migration versus the ongoing projected cost of keeping the on premise email archive.
Looking at the table above, we see that the 3 year cost of keeping the on premise email archive is $354,000 and the cost of migrating it to Office 365 is $100,000 (keeping in mind the ongoing cost of the archived data, once in Office 365, is zero). With these numbers we can calculate the return on investment (ROI): ($354,000-$0.00)-$100,000)/$100,000 = 254%. We can also see that the breakeven time of the investment is 6.5 months.
Considering the above results, migrating your legacy email archive to Office 365 is a great investment!
