I am upgrading Etabs 9.20 to 9.50. Some of the users are suggesting to keep the old version as well and their recommendation is below.
There is no reason that an alternate directory could not be made to separate the installations. Additionally, if version 9.5.0 is just a partial update, not a full installation, simply copy the 9.2.x directory, rename it, and install 9.5.0 over the top of that directory. Perhaps even call it ETABS 9_5_0 rather than the default ETABS 9 directory name under the Computers and Structures directory, then just point it to the appropriate license file.
We deploy our application using SMS but do you think this is a good practice to do what these users are telling us. I know if we just keep the default setting the Etabs 9.5 uninstalls the old version first and reinstalls the new one.
Thanks for the advice.
