The migration of part and file permission information, the mark for needing third-party migration server to support by source device and target device
The migration of file and file permission information between quasi- protocol realization source device and target device.Specifically, migration server from
Source device reads the authority information of file and file, then sets the authority information of the file of reading and file write-in target
It is standby.
In the prior art, it generallys use under type such as and carries out the migration of file permission information:
Mode 1, when file system supports different types of first authority information and the second authority information, migration service
Device is by supporting the first agreement of the first authority information to migrate the first authority information to target device, then, source from source device
Equipment obtains the second authority information to the first authority information conversion that migration obtains.
Mode 2, migration server, which first passes through, supports the first agreement of the first authority information to set the first authority information from source
It is standby to migrate to target device, then by supporting the second protocol of the second authority information to migrate the second authority information from source device
It, still, can be according to the second authority information to first moving after the second authority information that target device migrates after acquisition to target device
The first authority information moved is updated, this is because target device can default a type of permission of file based on the received
Information is updated the other kinds of authority information of file, so that the user's operation that all kinds of authority informations of file characterize
Permission is consistent.Therefore, mode 2 is substantially identical as mode 1, and the authority information to migrate after realizes permission migration.
However, the information content that the different types of authority information of file is included may be different, and weighed between different vendor
The rule of limit conversion is also different, causes in above two migration permission mode, the permission before authority information and migration after migration

A1 is migrated from source device to target device, and target device converts the first authority information A1 according to permission transform rule, raw
At the second authority information B1, using the second authority information B1 of generation as the file permission information saved in target device.It can
See, the second authority information B1 that target device saves occurs information compared to the second authority information B saved in source device and loses.
In another example the transformation rule in source device and target device between the first authority information and the second authority information not
Meanwhile user is updated the second authority information of file in source device, forms authority information B, source device is according to the first power
Transformation rule 1 between limit information and the second authority information converts authority information B, authority information A1 is generated, by the power
Limit information A1 is as the first new authority information.Then, migration server migrates authority information B to target device, and target is set
It is standby that authority information B is converted according to the transformation rule 2 between the first authority information and the second authority information, generate permission letter
A2 is ceased, using authority information A2 as the first new authority information.As it can be seen that in authority information and source device in target device
Authority information is inconsistent.
