Error description
If bin/WASPostUpgrade.sh is invoked from a profile root directory, migration process fails with a NullPointerException. WAS90.MIGR [10/08/2020 14:12:45:031 CDT] java.lang.NullPointerException com.ibm.ws.migration.utility.Upgr adeException: java.lang.NullPointerException at com.ibm.ws.migr ation.postupgrade.Restore.<init>(Restore.java:274) Caused by: java.lang.NullPointerException at com.ibm.ws.migration.common.D efaultOSInfo.readCmdLineFile(DefaultOSInfo.java:532) at com.ibm .ws.migration.common.DefaultOSInfo.<init>(DefaultOSInfo.java:153 ) at com.ibm.ws.migration.common.LinuxInfo.<init>(LinuxInfo.java:47)
Local fix
Use WASPostUpgrade.sh(.bat) from WAS_INSTALL_ROOT/bin instead of PROFILE_ROOT/bin
Problem summary
**************************************************************** * USERS AFFECTED: All users of IBM WebSphere Application * * Server Version to Version Migration Tools * **************************************************************** * PROBLEM DESCRIPTION: NullPointerException during * * WASPostUpgrade, readCmdLineFile in * * stack trace * **************************************************************** * RECOMMENDATION: If possible, run WASPostUpgrade from the * * WAS_HOME/bin directory. * **************************************************************** Problem is occurring because WASPostUpgrade is being run with a current working directory that includes the relative file path properties/version/profile.version, usually the profile's root directory. Due to the way WASPostUpgrade constructs a file path related to gathering OS info, this file may exist when WASPostUpgrade does not expect it to, causing it to pass a null user root to code that reads setupCmdLine.sh, which causes the error.
Problem conclusion
Migration was adjusted to properly check for null files before attempting to read the setupCmdLine script. WASPostUpgrade should now succeed regardless of the existence of properties/version/profile.version in the current working directory. The fix for this APAR is targeted for inclusion in fix pack 9.0.5.7. For more information, see 'Recommended Updates for WebSphere Application Server': https://www.ibm.com/support/pages/node/715553
