Best practices: - Make a backup of your LISTSERV directory. Our installation uses one directory tree C:\LISTSERV for LISTS, LOG, MAIN, SPOOL, TMP, and WWW. - Take a snapshot of your Windows VM (VMware virtual host) or use the Windows Recovery Point. - Notify power users or your support desk of planned outage. - Ensure you have the latest Windows patches. - Talk to your Windows AD administrators if you haven't done this before. - Follow the L-Soft upgrade procedure. matthew black california state university, long beach -----Original Message----- From: LISTSERV Site Administrators' Forum [mailto:[log in to unmask]] On Behalf Of Marshall, Clinton C Sent: Wednesday, July 01, 2015 7:54 PM To: [log in to unmask] Subject: Upgrading windows 64bit listserv v16.0 to LISTSERV 16.0 2014b - Hello, I am looking for some feed back regarding how long it has taken Administrators to upgrade their windows 64bit listserv v16.0 to 16.0 2014b I have a 13 GB List directory with 1519 Lists, any feed back would be appreciated, regards ############################ To unsubscribe from the LSTSRV-L list: write to: mailto:[log in to unmask] or click the following link: http://peach.ease.lsoft.com/scripts/wa-PEACH.exe?SUBED1=LSTSRV-L&A=1 ############################ To unsubscribe from the LSTSRV-L list: write to: mailto:[log in to unmask] or click the following link: http://peach.ease.lsoft.com/scripts/wa-PEACH.exe?SUBED1=LSTSRV-L&A=1 ############################ To unsubscribe from the LSTSRV-L list: write to: mailto:[log in to unmask] or click the following link: http://peach.ease.lsoft.com/scripts/wa-PEACH.exe?SUBED1=LSTSRV-L&A=1
