CRONw - Update
Version 2.0 is considered incompatible with the old 1.x versions of CRONw. You'll need to reinstall CRONw. The crontab format is unchanged so you may use the old crontab with CRONw 2.0.
To update an existing copy of CRONw, follow these 1-2-3 instructions. Please see if you have to pay special attention if you're upgrading from a special version.
Existing crontab file(s)
Your existing crontab file(s) won't get overwritten, because as of version 1.3beta a default crontab isn't delivered any longer. Only if no crontab file exists, CRONw will create an empty one from scratch for you.
Updating from versions prior to 2.0 beta
The naming of the source files has changed with 2.0. You may remove all files in the old CRONw directory (keep a copy of your crontab!) and copy the new ones into it. Please rename your crontab file to "crontab.txt".
Because the name change please remove the cron service prior to installing (perl cronHelper.pl --remove).
The logging format has changed, so you might consider updating any logfile parsing scripts you're eventually using. You may change the logfile format by editing log.conf
See "Debugging your installation" in INSTALL.txt.
