Good afternoon, I recently upgraded from version 2.3.0 to 2.3.1 through composer It happens that some modules were disabled during the upgrade, I would like to know the reason and what I do with them (remove?)
List of disabled modules:
Magento_InventoryDistanceBasedSourceSelection
Magento_InventoryDistanceBasedSourceSelectionAdminUi
Magento_InventoryDistanceBasedSourceSelectionApi
Magento_InventoryElasticsearch
Magento_InventorySetupFixtureGenerator
It looks like you disabled inventory management
It's for Multi Source Inventory (MSI) project Check do you have this in your composer.json
magento/inventory-composer-metapackage = ^1.1.0
And from this link above
2.2.X Magento installation to Magento 2.3.X, Inventory Management modules will be disabled by default.
The modules you listed belong to MSI 1.1.1 which is deployed along with Magento 2.3.1. All these modules supposed to be enabled if MSI was enabled before. If it was disabled beforehand on Magento 2.3.0 - the new modules should be disabled as well. You can read more about this here - https://github.com/magento-engcom/msi/wiki/MSI-Release-Notes-and-Installation#msi-110
Created corresponding ticket for your case - here https://github.com/magento-engcom/msi/issues/2217 don't hesitate to provide more details
