In order to change from one version of Lawson to another (i.e., from Universe 2.2 to Insight 7.0 and back) you'll need to make sure the /etc/lawson.env file is configured correctly.

In addition, you'll need to make sure that the $LAWDIR/lawson.env file contains an entry for the variable LAWVER. This variable will control switching from one version to another. For your version 2.2 installation I would set LAWVER to 2.2 and for your 7.0 installation I would set LAWVER to 7.0. This is what the sample /etc/lawson.env file will assume.

Also included in the /etc/lawson.env file is the setup to show your current directory in your prompt. We'll set PS1 to (`hostname`-X##):\${PWD}> where X## is your version of Lawson.

One more thing before you look at the file. You'll need to chmod +x to the $GENDIR/bin/cvx file in order to switch from 7.0x to 6.1x and you'll need to copy $GENDIR/bin/cv* from your 7.0x installation to your 6.1x $GENDIR/bin directory.
