Good morning,
We have moved our M2 installation to a new server, and from that moment I get this error, when trying to open the migration page.
CDbConnection.connectionString cannot be empty
We have done a first migration, and I want to execute a delta migration.
Hope you can help my with the occuring error.
Best regards,
Roy

Hi Roy,
We have done a first migration, and I want to execute a delta migration.
It seems that you have changed database credentials after moving to a new server. Please re-update with the correct database credentials in the configuration file of our migration tool at: pub/ub-tool/protected/config/db.php

Good morning,
When moving to the new server, I re-installed the webshop, from the composer.json.
Obviously it didn’t have the required config files in pub/ub-tools.

Hi there,
I re-installed the webshop, from the composer.json.
It’s pity that we did not support installation via composer for our UB Data Migration Pro module yet. The only installation option available was mentioned in our Readme manual (included with your download package).
Since you moved your old M2 instance to a new server, please note additional steps below:
- You need to back up all the folder at pub/ub-tool
- Re-update your site credentials as per Mall’s reply #1 above.
Hope that helps.
