<p>Adnan,</p>
<p> You can have both Trnsys17 and Trnsys18 installed at the same
time on the same computer. In your place I would leave my Trnsys17
projects where they are and make copies of them to move to the
\Trnsys18 directory. You can always make a backup of the
\MyProjects\ directory too and store it somewhere safe as a
backup.<br>
</p>
<p>kind regards,</p>
