You can have many Tekla Structures versions on your computer. When you install and start using a new version, you do not need to uninstall the older versions and you can keep using them. Service packs are cumulative updates, so they replace the previous service pack installation for the same Tekla Structures version.
We recommend that you complete any models you are already working on using your current version of Tekla Structures. Once you save a model in the new version, you cannot open it in the previous versions anymore.
You can download the installation packages from the Tekla Downloads service.
Complete the upgrade in this general order (follow the links in the text for detailed instructions):
Update the Tekla license server. The updated version replaces the existing version you have installed.
Renew your licenses as explained in Renew a Tekla license.
The renewed licenses can be used with the version indicated on the license and any previous versions that are compatible with your installed license server version.
You can have many Tekla Structures versions and environments on your computer. When you install and start using a new version, you do not need to uninstall the older versions.
You can use the Migration Wizard tool to copy some of the personal settings to the new version. You can skip the copying if you do not want to copy the settings, or if you want to copy the settings from some other Tekla Structures version than suggested in Migration Wizard.
In the new Tekla Structures version, you can use the information you have customized in the previous version. We strongly recommend that you create project and firm folders, and store the files you customize in these folders. Tekla Structures does not replace the files in project and firm folders when you install a new version. If you do not use project and firm folders, you need to transfer the customized information to the new version manually.
