Tools build in CF5 will be working with CF8, what is the difference?

FYI, my Server = nt7 is old server supporting Cold Fusion 5, and that is where current website site is sitting at. This server is old Windows NT type of environment.

I have a new Server = vws3.primus.ca – hosts the sql6.magma.ca (SQL2000) database used for the above site. The server is Windows/UNIX blend of environment,

So my question are:

My website and tools are build in CF5, hosted on vm machine windows nt and SQL Server 2000.

I have another hosting with cf8. I'd like tomove my website and CF tools (build in cf5) to my new server so here is my questions ???

1. What is the current CF language version?  

2. What is the difference between cf5 and cf8.... ?

3. So if I've decided to move my website to another platerform Windows, SQL 2005 and they have Cf8 will my cf5 tools on my website work with the new version of ColdFusion? it is supported ?

tx.

Current version is CF9

CF5 & 9 are probably only somewhat compatible

rather than rehash your best bet is this resource

http://blog.joshuaadams.com/index.cfm/2008/9/3/Migrating-from-ColdFusion-5-or-older-to-ColdFusion-8 

(which has been updated to cf9)

you don't say what your "cf5 tools" are so it's impossible to say whether they will work with CF9

It's custom code build in cf5

Well that's impossible to answer. Your code may work, it may not.

What I can say is this. CF5 was based on very different technology. The change to the current java based CF happened in CF6 (MX) and as a result there were quite a few differences post CF5

Read the first chapter of this http://download.macromedia.com/pub/documentation/en/coldfusion/mx7/cfmx7_migrating.pdf

Depending on how complex your code is, it may be a quite simple transition, or it may be quite involved. You will for sure have to set up all of your datasources, task and anything else in cfadmin as there is no migration utility from cf5. Once you've done that, alkl you can do is drop in your code, see what's broken and fix it.
