How to transfer the Processes/Product system to another computer and different versions of databases?

Question

Hello community members!

I have a question would like to ask for your kind help as mentioned in the title.

For your better understanding, I explain my situation here:

1. I built my LCA model in openLCA 1.10.3 with Ecoinvent 3.7.1 consequential system model using my old computer. 

2. I have created several Processes, Flows, and Product systems that I used to calculate the LCIA in the old computer.

3. I am using a new computer now, I have installed openLCA 1.10.3 already.

I want to transfer the already established Processes, Flows, and Product systems from the old computer to this new computer. How can I do that properly?

Since I know that Ecoinvent has released a new 3.8 database, I am considering two options - to continue using v 3.7.1 or v 3.8 (is that even possible?) in the new computer.

Thank you for your help in advance!

You may export your product system to a new database.

Hi, to migrate to a new computer, backup the databases you want to continue using from within openLCA, on the old computer, you will create zolca files, for each database one, copy these to the new computer, install openLCA on the new computer, and restore the databases from within openLCA.

For migrating to ecoinvent 3.8 from 3.7.1. this is possibe, we explain this in the documentation for ecoinvent 3.8, https://nexus.openlca.org/ws/files/22528.

Best wishes,

This doesn't work for me. Every time I use the restore database option Ii get an error message:

"Could not get the version from the database. Is this an OpenLCA database"

It was backed up as a zolca file.
