The Autodesk web site has now been updated with the updated AutoCAD Migration Tools. There is also a migration best practices document.

Best Practices for AutoCAD Migration PDF (62 KB)
Import your menus, toolbar items, and keyboard shortcuts (accelerators) from previous versions of AutoCAD into AutoCAD 2005.
Convert any AutoCAD or AutoCAD-based drawing file to AutoCAD Release 14, AutoCAD 2000, AutoCAD 2000i, AutoCAD 2002, AutoCAD 2004, and AutoCAD 2005 file formats.
Convert your customized menus, files, command aliases, and layer states, and script with greater ease.
Tools included
The following four tools are included in the Autodesk Customization Conversion Tools download:
1. AutoLISP Compatibility Analyzer details AutoCAD® 2004 and AutoCAD® 2005 compatibility issues found in AutoLISP and Menu LISP files. AutoLISP Compatibility Analyzer searches for known AutoCAD 2004 and AutoCAD 2005 compatibility issues. When an issue is found, an explanation of the compatibility issue and suggestions on how to correct it are provided.
2. Command Alias (PGP) Porter designed to help you bring your custom command aliases from previous versions of AutoCAD into AutoCAD 2004 or AutoCAD 2005. You can also use this tool to add, replace, or remove command aliases from any AutoCAD PGP file.
3. ScriptPro takes AutoCAD scripting to a new level with an easy-to-use interface, logging, reusable project files, enhanced scripting with new keywords and utilities, and robust error recovery. Using ScriptPro you can apply a set of commands to multiple drawings by simply specifying a script file and the list of drawings that you would like to apply the script to.
4. Layer State Converter allows you to convert between the layer states created by LMAN (one of the AutoCAD® Express Tools) and the saved layer states introduced in AutoCAD® 2000i software. To use Layer State Converter, type one of the following commands on the AutoCAD command line:
CONVERTLS – Converts AutoCAD layer states to LMAN layer states.
CONVERTLMAN – Converts LMAN layer states to AutoCAD layer states.
Hi Shaan, where is that document “Best Practices for AutoCAD Migration PDF” ?
Ignacio,
It is on the same Migration Tools page.
http://www.autodesk.com/migrationtools
or direct

Sincerely,
Shaan Hurley
I’m afraid the Migration Tools links all seem to be broken??
Not sure of any reasons as the links are working for me from my home connection.
Cheers,

Hmm… that really is quite strange. I had a look on the FTP server too (ftp://adeskftp.autodesk.com/ProdSupp/downloads/ etc.) and whilst I can see a lot of files, I definitely can’t see any of the migration tools. The last file that I can see before the spot where “cust_migr.pdf” should be is CivilSeries2004SaveAsEnabler.exe.
A Windows Explorer search of the whole FTP site didn’t turn up any results for “cust_migr”, either.
Shaan,
Just tried to access the lisp migration tools at ftp://adeskftp.autodesk.com/ProdSupp/downloads/CCTSETUP.EXE
The link is broken, and has been for a while. Where else can I get the tools?

Art,
I am not sure what could be going on as many have successfully downloaded as have I from my home machine. I will check with the web team and see if they are aware of any issues. Also there is a feedback on the website at the bottom of the autodesk.com web pages that submits the feedback to the team in charge.
I was able to download again just now by right-click on the link and save as option in IE.
Sincerely,

Hi Shaan,
I am a big proponent of ScriptPro for various reasons. Unfortunately, it is not fully compatible with ADT 2005.
When running scripts that plot files, ADT 2005 cancels prematurely and you get a partial plot. One can reproduce this error with large files that take a few seconds to plot. Autodesk have said that the problem lies deep within the code and that it would require a complete overhaul, which they do not intend to do. Bummer. I have to start shopping around for another program.
The new publish command isn’t versatile enough. For instance I liked using ScriptPro to set imageframe to off before plotting. Or choose which files in a list to skip. None of these can be done in publish. Thanks
