When attempt to upgrade from 7.0.2 to 7.0.8, TDV services are not getting started after gradating, even though up-gradation script showing successful.

Root Cause: Not able to find the logs directory path to write the output, as there is different logs folder structure in 7.0.2 and 7.0.8

Following these below steps to fix the issue:

1) TDV Server : Stop the TDV Repository, TDV Cache and TDV Monitor processes.
2) Apply the hotfix of TDV Server 7.0.8
3) Edit the following file(s):

           TDV Server :

Edit files <INSTALL_DIR>/repository/data/postgresql.conf and   <INSTALL_DIR>/repository/data_cache/postgresql.conf

Replace " log_directory = '../../logs/cs_repository'" with "log_directory = '../../logs'"

Replace " log_directory = '../../logs/cs_data_cache' " with  "log_directory = '../../logs'“

4)   UNIX and Window installations:

  Execute the 7.0.7 or higher TDV Server

  Examples:   $ cd <INSTALL_DIR>; ./bin/cis_upgrade_patch.sh (TDV upgrade)
