Migrating data between heterogeneous cloud block devices

A management server, communicatively coupled with network equipment that is part of a communication network, comprising a processor configured to process executable instructions that, when executed by the processor, facilitate performance of operations, comprising:

• generating a data copy comprising application data corresponding to first block storage equipment communicatively coupled with the network equipment;
• copying, during a migration period, the data copy to second block storage equipment communicatively coupled with the network equipment;
• generating, during the migration period, a first change log configured to store first change information corresponding to at least one data change comprising first changes, directed to the first block storage equipment, to be made to the application data;
• receiving at least one first log characteristic indication indicative of at least one first log characteristic, corresponding to the first change log, associated with storing of first change information to the first change log during the migration period;
• analyzing the at least one first log characteristic with respect to at least one cut-over criterion to result in a first analysis result;
• based on the first analysis result being that the at least one cut-over criterion has been satisfied by the at least one first log characteristic, directing at least one data change to be made to the application data resulting in at least one first directed data change comprising the first change information, the directing comprising copying, after the copying of the data copy to the second block storage equipment, the first change information to the second block storage equipment during a first-change-log-copying period;
• generating, during the first-change-log-copying period, a second change log comprising second change information corresponding to second changes to be made to the application data;
• receiving at least one second log characteristic indication indicative of at least one second log characteristic, corresponding to the second change log, associated with storing second change information corresponding to at least one second change to be made to the application data during the first-change-log-copying period;
• analyzing the at least one second log characteristic with respect to the at least one cut-over criterion to result in a second analysis result;
• and
• based on the second analysis result being that the at least one cut-over criterion has been satisfied by the at least one second log characteristic, managing at least one data change to be made to the application data after the first-change-log-copying period to the second block storage equipment.

A non-transitory machine-readable medium, comprising executable instructions that, when executed by a processor of a computer server communicatively coupled with a communication network via network equipment, facilitate performance of operations, comprising:

• generating a data copy comprising application data, stored according to a first block drive format by a first cloud block drive communicatively coupled with the communication network;
• copying, during a first journal creation period, the data copy to a second cloud block drive, communicatively coupled with the communication network, wherein the application data corresponding to the data copy is to be stored by the second cloud block drive according to a second block drive format;
• copying a first journal to the second cloud block drive during a first journal copying period, wherein the first journal comprises first change information, to be made to the application data, directed to the first cloud block drive during the first journal creation period, and wherein the first change information is to be stored by the second cloud block drive according to the second block drive format;
• analyzing a first journal characteristic, corresponding to the first journal, with respect to at least one cut-over criterion to result in an analyzed first journal characteristic;
• based on the analyzed first journal characteristic indicating that the at least one cut-over criterion has not been satisfied by the first journal characteristic, copying a second journal to the second cloud block drive during a second journal copying period, wherein the second journal comprises second change information, to be made to the application data, directed to the first cloud block drive after the first journal creation period, and wherein the second change information is to be stored by the second cloud block drive according to the second block drive format;
• analyzing a second journal characteristic, corresponding to the second journal, with respect to the at least one cut-over criterion to result in an analyzed second journal characteristic;
• based on the analyzed second journal characteristic indicating that the at least one cut-over criterion has been satisfied by the second journal characteristic, pausing, during a cut-over period, the directing, to the first cloud block drive, of the at least one data change applicable to the application data during the second journal copying period;
• and
• directing, to the second cloud block drive, the at least one data change, applicable to the application data during the second journal copying period, to be stored by the second cloud block drive according to the second block drive format.
