The effort of moving a particular subscriber company's existing data and users into a hosted cloud solution is referred to as 'onboarding'. It's essentially just the cloud version of migration from one solution to another. But there is one crucial difference in the fact that data are crossing from one provider to another, typically from the subscribing company's prior on-premises solution to the SaaS vendor's cloud solution. Two very important considerations result. First, the volume of data to be migrated may well be so large, a transfer via the internet would take unacceptably long. We have other options, such as shippable physical storage devices, available for that reason. Second, because the data come from another environment, the Cloud vendor can't assume they have been subject to the same level of virus and malware scanning required in the data center environment. For that reason, we undertake scanning of subscriber data as part of the onboarding process. This is clearly necessary, as we have in fact found incidences of 'unwanted' content in subscriber data submitted for onboarding. It is key to leverage scan engines updated with the latest virus protection information. With these and other safeguards not described here, we can offer a quick, proven onboarding process.
