Unfortunately you can't for a few reasons. We did not make this decision lightly.....it was a project that got very far and then was ended. Because the new version is so much more detailed there are many areas where direct importing of an old file will not work. For example, consider loads and load combinations. Version 5.8 considered load types such as "Live Load" and "Short Term Load". But there is no direct way to map these older load types into the current version, because the new version has two different live load types and several short term load types. The only solution to this particular conundrum was going to require more work on the part of the user to simply **map** the data, than the work it would take to **re-enter** the data in the new version. And this was just one of many hurdles. There are a lot of little things that don't map between the two versions. The new version has every solver rewritten and uses the latest codes. This means the calculation results could all be slightly different (or very different) than they were in previous versions. Although this represents a quantum leap forward for the software, it would likely invite a great deal of confusion as engineers would be inclined to compare and reconcile two sets of printouts. --- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com. ## Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation by asking a question. Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters: ``` GET https://enercalc.com/docs/sel-faq/using-the-software/files/version-58-files.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
