Question: How to avoid schema failure after upgrade?


Answer: 


The schema changes can fail or timeout, if the database is busy processing during the upgrade. 


To avoid the schema failure, perform these steps before you upgrade:

  1. On all the nodes, run the  vsh stop sudo command.
  2. Upgrade the analytics nodes first, then upgrade the search nodes.
  3. Run the  /opt/versa/scripts/van-scripts/schema-check.sh command to check if schema is up to date.
