As per Pega719 upgrade guide, we are upgrading from single to split schema. Currently at Step 8 (page #48) of the document where we are trying to trigger off the migration via unix command on the database server. But soon as we type "./migrate.sh" a syntax error is thrown by the system that says "Error at line 21. j=$ - unexpected". Has anybody got an idea on this as we've checked the bash, and 'JAVA_HOME' directory to have been set with JDK.
