Sharing this info for people who run into problems upgrading SEPM to the latest version using SQL 2014 and not using a "strong" password
I moved my SEPM database from SQL 2008 sp2 to SQL 2014 because SEPM 14.1 cannot work with SQL 2008 sp2
Connected my SEPM 12.1 to the new SQL 2014 without any issues, then I started the upgrade process to SEPM 14.1. All went wrong from there. I could not upgrade my SEPM, the installation for SEPM went ok, the migration wizard connected to the database ok but did not complete all the steps.
I found in a Tomcat log the following error: THREAD 21 SEVERE: com.microsoft.sqlserver.jdbc.SQLServerException: Password validation failed. The password does not meet Windows policy requirements because it is not complex enough.
I changed the password for my SEPM DB to a more complex password, and started the migration wizard again. Now it runs and completes all steps successful.
Possibly the new Tomcat webserver in combination with SQL 2014 using a password not strong enough causes this issues. Its not only SQL 2014 because I could connect with the older SEPM 12.1 to the new database without any issues
Hope this helps people running into similar issues. I spoke with technical support for about 4 hours today but they couldnt fix the issue. I found the log file entry error and made the password complexity changes.
