Information processing apparatus, information processing system, and non-transitory computer readable medium storing program

An information processing system comprising:

• the information processing apparatus including
• an acquiring part that acquires a file structure at a migration source and one or more identification information items each of which identifies a file at the migration source,
• a copying part that copies the file structure and the one or more identification information items to a migration destination before migration of content data of one or more files at the migration source, and
• a switching part that, in response to detection of an operation on a file corresponding to one of the one or more identification information items copied to the migration destination by the copying part, switches an access destination to the file at the migration source if a migration time to complete migration of content data of the file and finish the operation is equal to a predetermined duration or more;
• and
• a migration-source manager that serves as the migration source and that manages a plurality of files to be migrated in a predetermined file structure together with identification information items each of which identifies one of the plurality of files to be migrated.

A non-transitory computer readable medium storing a program causing a computer to execute a process for information processing, the process comprising:

• acquiring a file structure at a migration source and one or more identification information items each of which identifies a file at the migration source;
• copying the file structure and the one or more identification information items to a migration destination before migration of content data of one or more files at the migration source;
• and
• in response to detection of an operation on a file corresponding to one of the one or more identification information items copied to the migration destination by the copying part, switching an access destination to the file at the migration source if a migration time to complete migration of content data of the file and finish the operation is equal to a predetermined duration or more.
