Specific embodiment
Generally, source device and target device are the equipment of different vendor, are difficult to directly enter style of writing between different vendor's equipment
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 write target of the file of reading and file
It is standby.
In prior art, the migration of file permission information is generally carried out in the following way：
Mode 1, when file system supports different types of first authority information and the second authority information, migration service
Device is by supporting that the first agreement of the first authority information migrates the first authority information to target device, then, source from source device
The first authority information conversion that equipment is obtained to migration obtains the second authority information.
Mode 2, migration server is first passed through supports that the first agreement of the first authority information sets the first authority information from source
It is standby to migrate to target device, then by supporting that the second protocol of the second authority information migrates the second authority information from source device
To target device, but, after the second authority information that target device is migrated after acquisition, can be according to the second authority information to first moving
The first authority information for moving is updated, this is because target device can give tacit consent to a type of authority according to the file for receiving
Information is updated to the other kinds of authority information of file, so that the user operation that all kinds of authority informations of file are characterized
Authority is consistent.Therefore, mode 2 is substantially identical with mode 1, is to realize that authority is migrated according to the authority information of rear migration.
However, the quantity of information that the different types of authority information of file is included may be different, and weigh between different vendor
The rule of limit conversion is also different, the authority before authority information and migration in causing above two migration authority mode, after migration
Information is inconsistent.
For example, the first authority information of file is A1, and the second authority information of file is B, the second authority information B by B1 with
And B2 compositions, wherein, according to the transformational rule between the first authority information and the second authority information, A1 can be converted to B1, and B1 can
To be converted to A1, therefore, the quantity of information of the first authority is less than the quantity of information of the second authority.Migration server is by the first authority information
A1 is migrated to target device from source device, and target device is changed according to permission transform rule to the first authority information A1, raw
Into the second authority information B1, the file permission information that the second authority information B1 for generating is preserved as in target device.Can
See, the second authority information B1 that target device is preserved occurs information and loses compared to the second authority information B preserved in source device.
Again for example, the transformational rule in source device and target device between the first authority information and the second authority information is not
Meanwhile, user is updated to the second authority information of file in source device, forms authority information B, and source device is according to the first power
Transformational rule 1 between limit information and the second authority information is changed to authority information B, generates authority information A1, and this is weighed
Limit information A1 is used as the first new authority information.Then, migration server migrates authority information B to target device, and target sets
It is standby authority information B is changed according to the transformational rule 2 between the first authority information and the second authority information, generate authority letter
Breath A2, using authority information A2 as the first new authority information.It can be seen that, in the authority information in target device and source device
Authority information is inconsistent.
Believe with the authority before file migration to solve the authority information present in prior art after above-mentioned file migration
