Issue
Many customers still have a requirement to run Lonmaker 3.13, but have project specific issues related to software fixes in newer version of LNS Server, and an LNS Server upgrade is required.
Product Line
TAC Vista
Environment
- Echelon Lonmaker
- LNS
Cause
Older versions of Lonmaker 3.1 and LNS server had multiple defects that were addressed in later version of Lonmaker Turbo and LNS Server Turbo. However, it is possibly to run Lonmaker 3.1 and only upgrade the LNS server engine to take advantage of software fixes over time.
Resolution
NOTE: Any LNS Server version older than 3.10 needs to first be upgraded to 3.2x before 3.2x service packs can be installed. Also, please take into consideration that after upgrading the LNS Server on a system that any other system that needs to open that same database will have to be at the same version or higher. For example: a database upgraded to 3.27 can not be opened on the machine running 3.08.
