Needless to say, it’s a very good idea to backup your database before the upgrade and and to have an emergency plan in case things go wrong.
#Upgrade snagit 9 to 11 install#
Yum install postgresql11 postgresql11-contrib postgresql11-devel postgresql11-libs postgresql11-server
#Upgrade snagit 9 to 11 update#
Luckily, this process is quite straightforward and all the hard lifting is done by the postgresql update tool. I had to update an already unsupported Postgresql instance running on version 9.3 to the latest version 11.
