This scenario could have several risks, as follows:

• The remote IT facilities are not only limited, but they lack in something; space could be a real constraint, but also a risk. For example, in the case of a migration, maybe there isn’t enough space for the new systems, or rack mounting of the physical servers is not possible, for example, because the rack is not deep enough to host full-length servers.
• You have to also consider that power supplies and UPS could be insufficient in size, switches may lack in redundancy or performance (maybe they have just 1 Gbps ports), and cooling and HVAC may not be present at all.
• Actual business continuity plans could be limited and backup and recovery could be problematic, and they must be carefully addressed. Of course, this limitation in IT facilities may also mean limited physical security; in some cases, the IT facilities are not closed in a secure room or access controls are not enforced.
• Finally, one of the major risks could be related to the geographic network connection with the main (or the central) office; bandwidth or latency assumptions could be wrong and must be verified to be sure to have an effective central management and to check which kinds of services could be centralized and which must be localized.
