How to understand the version number and identify the database version

A typical TM Master V2 version number looks like this:

2.662.7636.16913

If we break it down, the different number sequences have the following significance:

2.662.7636.16913

This is the main version number (hence TM Master V2). If the main version of two installations differ, then their databases are not compatible. To upgrade requires a manual conversion of the database. Please contact us for more details if you are interested in having this done.

2.662.7636.16913

This is the database version number. To upgrade from one database version to another (for example from 660 to 662), an automated upgrade of the database is required.

Different database versions are not forward compatible for replication, so it is not possible to replicate data between an office and a vessel that have different database version numbers. This means that to perform a successful database upgrade, the entire fleet needs to be upgraded in one operation.

The TM Client and TM Service are not compatible with different database versions. This means that all TM Clients and TM Services must be the same database version as the database they connect to in order to function.

2.662.7636.16913

This is the hotfix version number (also known as the patch version number) which does not generally affect the structure of the database. To upgrade from one hotfix version to another does not require a database upgrade.

Different hotfix versions are compatible for replication, so it is possible to replicate data between an office and a vessel that has different hotfix versions as long as the main and database version numbers are the same.

The TM Client and TM Service are compatible with different hotfix versions, so as long as the main and database versions are the same any combination of hotfix versions will generally be able to connect to and work with the database.
