When updating Acctivate to a new version, a user has the option to use the regular Update or the Cumulative Update. This article will explain the difference between the two, and when they should be used.
The Update contains considerably less data than the Cumulative Update, so it is a much smaller download file. An Update is going to update the logic in the Acctivate database to be current. This will fix issues found in previous versions, as well as introducing some new logic for new enhancements. The advantage to using an Update over a Cumulative Update is that the download is a much smaller file. If nothing is changed or different in Acctivate aside from the database logic, this will be a faster download and will take up less space on the drive. Updates are commonly used when doing a service pack update. An example would be updating from version 10.2 SP1 to 10.2 SP2.
The Cumulative Update includes the same logic updates to the database, but the Cumulative Update will also do a check on everything in the Acctivate folder to find things that are missing, and to install new things required to run the new version. For instance, the Cumulative Update will check the Client Files folder in the Acctivate folder to make sure that any component files/drivers required to run that version of Acctivate are all installed. If something is missing, the Cumulative Update will make sure that it gets put back. If a newer version of some component is required for the newer version, the Cumulative Update will make sure that it gets installed. Cumulative Updates are commonly used when doing minor and major updates. An example would be updating from version 10.1 to 10.2, or 10.1 SP2 to 10.2. Cumulative Updates are required when doing a major update. An example of that would be an update from version 10 to version 11, or version 10.2 Sp2 to version 11.
