How to properly merge two databases

Question

Hi,

I've been using and working on ecoinvent 3.7.1 until here and i ordered the v3.8 and dowloaded it. So i went to my current database (3.7.1), right clicked on it and selected 'import' and then "entire databse". I chose the cutoff method (don't really know the difference with regionalized or not) and then imported it.

But when calculation starting, it failed and in the log file here is the message :

I tried to check db and there are 54k errors when validate it

So how to properly merge two databases ?

Thanks in advance,

Regards

Yes, good question, the merging you are referring to is maybe more an update of an older database to a newer one, right? We will be preparing a script to do this, for e.g. ecoinvent 3.9, soon, to be executed in openLCA. So far it is also script-based but done by us here for some cases.

Hello and thank you for the answer.

Yes, it's more an update from the previous version to the newest.
So until now, i can't really use the v3.8 just bought until the script is being realsed ?

Hi,

Still not able to update from 3.7.1 to 3.8. Do you have a an idea how to perform an update until waiting the 3.9 and its script?

Thanks

We have provided an upgrade from 3.7 to 3.8 to some clients, but they shared the entire database with us - we could do this for you too if you are interested. But 3.9 is around the corner (we received the files except APOS from ecoinvent finally 10 days ago or so and are now working on them).

Hello and I wish you a happy new year.

The 3.9.1 has been released and I'd like to know where can we find the script for the update from 3.7.1 to 3.9.1.

Please let me know.
