<div class="markdown_content"><p>Yes you are correct. I may have posted too quickly. I found that when testing the open project with an empty V3.0 project the conversion task told me there were errors and I was only seeing the main name of the project in the tree view. I made a dumb mistake that all I needed to do was change the view and all the FB showed up.</p> <p>It seems the only conversion is through opening a project/lib? I was not able to use the import function.</p> <p>Is there anything that can't be imported from V2.3 to V3? Do visualizations still work? I have imported them but I question if they still function.</p> <p>So yes I take back my earlier statement about the conversion of V2.3 to V3. It seems to be working well enough.</p> <p>But there is no way to go from V3 to V2.3 at least with FB and libraries that are user created? Assuming because a few main reasons are new Keywords and export file is in XML format? </p> <p>I'm trying to figure out which environment to develop FB and libraries to do my best to make them cross compatible.</p></div>

<div class="markdown_content"><p>The only problem I had when opening a V2.3 application in V3 was that I needed to have a PLC (or device) chosen as target. When the V2.3 application had the target "none" the conversion did not work (correctly). These projects contained all programming languages.</p></div>

<div class="markdown_content"><p>Am I crazy or is the best import/export of V2.3 to V3.0 or vice versa cut copy paste (CCC)? The open project of V3.0 and the conversion wizard just doesn't work. I understand the changes in V3.0 over V2.3 but now since I have to support both it is getting confusing which version I should start with especially if the FB/Library needs to work in both systems? Maybe I should write my own FB/library converter? Any thoughts? Has anyone had good success with this yet?</p></div>
