Dependency-based software upgrading

A system comprising:

• a processing unit;
• and
• a memory coupled to the processing unit and storing instructions thereon, the instructions, when executed by the processing unit, performing acts including:
• identifying a target software product that depends on a plurality of software products;
• determining respective dependency degrees between the plurality of software products, wherein the determining is based on correlation of property information related to a plurality of upgraded versions of the plurality of software products;
• dividing the plurality of software products into a plurality of groups of software products based on the respective dependency degrees, each group comprising at least one of the plurality of software products;
• dividing a first group of software products from the plurality of groups into a plurality of sub-groups of software products, each of the plurality of sub-groups comprising at least one pair of software products having a prerequisite relationship or comprising a standalone software product having no prerequisite relationship with other software products;
• determining candidate upgrade combinations based on the grouping of the plurality of sub-groups, wherein for each candidate upgrade combination a particular sub-group of software products is all update or not updated;
• determining a plurality of test scores associated with the candidate upgrade combinations, each test score indicating a performance enhancement degree of the target software product achieved by installing at least one upgraded version of at least one software product according to a respective one of the candidate upgrade combinations;
• and
• determining a target upgrade solution for the target software product based on the plurality of test scores, the target upgrade solution indicating upgrading a first sub-group of the plurality of sub-groups and not upgrading a second sub-group of the plurality of sub-groups, wherein the first sub-group includes multiple software products.

A computer program product, the computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by an electronic device to cause the electronic device to perform acts comprising:

• identifying a target software product that depends on a plurality of software products;
• determining respective dependency degrees between the plurality of software products, wherein the determining is based on correlation of property information related to a plurality of upgraded versions of the plurality of software products;
• dividing the plurality of software products into a plurality of groups of software products based on the respective dependency degrees, each group comprising at least one of the plurality of software products;
• dividing a first group of software products from the plurality of groups into a plurality of sub-groups of software products, each of the plurality of sub-groups comprising at least one pair of software products having a prerequisite relationship or comprising a standalone software product having no prerequisite relationship with other software products;
• determining candidate upgrade combinations based on the grouping of the plurality of sub-groups, wherein for each candidate upgrade combination a particular sub-group of software products is all update or not updated;
• determining a plurality of test scores associated with the candidate upgrade combinations, each test score indicating a performance enhancement degree of the target software product achieved by installing at least one upgraded version of at least one software product according to a respective one of the candidate upgrade combinations;
• and
• determining a target upgrade solution for the target software product based on the plurality of test scores, the target upgrade solution indicating upgrading a first sub-group of the plurality of sub-groups and not upgrading a second sub-group of the plurality of sub-groups, wherein the first sub-group includes multiple software products.
