Hi OCS support team,
We are using OCS for the past few years and we have many devices registered with it and OCS Inventory is handling the device management ( the version we are using is 2.05) . Now we have planned to go for upgrade to 2.5.x.
To upgrade from 2.0.5 ( version we are using it ) to 2.5 ( latest version released by ocs inventory) following the sequence of upgrade
step 1) upgrade from 2.0.5 to 2.1.x
Step 2) 2.1.x to 2.2.
Step 3) 2.2.x to 2.3.x
Step 4) 2.3.x to 2.4 and then 2.5.
- upgrade from 2.05 to 2.1.1 is successful
- Upgrade from 2.1.x to 2.2 is having some issues due to some database fields are missing from the old version. For example in the table accountinfo_config , new column added (default_value) which does not exist in older version (2.05/2.1.1) due to that ocs reports web console failed to retrieve data.
Can you please suggest the workaround and other options? to upgrade from 2.05 to 2.5.x ( version to version) with db field changes and without any loss of data
