Data migration method and apparatus

A communication device, comprising:

• a first control board slot;
• a first control board inserted into the first control board slot;
• and
• a second control board slot;
• wherein the first control board is configured to, after a second control board is inserted into the second control board slot, receive type information from the second control board, to determine whether the type information of the second control board and type information of the first control board are the same;
• and
• wherein the type information of the second control board and the type information of the first control board are different, the first control board is configured to send configuration data stored by the first control board to the second control board to cause the second control board to utilize the configuration data to perform a configuration.

A control board configured to be inserted into a first control board slot of a communication device having a second control board slot, the control board comprising:

• a receiving unit;
• a comparing unit;
• and
• a sending unit;
• wherein the receiving unit is configured to, after a second control board is inserted into the second control board slot, receive type information from the second control board, and
• wherein the comparing unit is configured to determine whether type information of the current control board and the type information of the second control board are the same, and
• wherein the sending unit is configured to send configuration data stored by the control board to the second control board when the type information of the control board and the type information of the second control board are different, to cause the second control board to utilize the configuration data to perform a configuration.
