The numbering sequence and content of sections between the 1994 and 2000 standards are different.  I don't think you can just add the new sections, your entire QMS will probably have to be rewritten.

We were going to renumber everything.  My contention is that the elements that remain from -1994 have been changed substantially enough that our existing operating procedures will no longer be in conformance with the standard.  I can't see where just pasting in the elements in -2000 that did not exist in the -1994 standard will bring our quality operating procedures into compliance.

I agree that it will not be a simple cut & paste process, but nothing has really been added, just rearranged and simplified.  Your registrar should be able to provide you with a list or conversion chart that breaks down the requirements of ISO9001:2000 and how the elements of ISO9001:1994 fill those requirements.  For example:

New 4.1--> requirements of old 4.2.1
New 4.2--> requirements of old 4.2.1,4.2.2,4.5,4.16
New 5.1--> requirements of old 4.1.1
New 5.2--> requiremetns of old 4.3.2
New 5.3--> requirements of old 4.1.1
New 5.4--> requirements of old 4.1.1, 4.2.3
New 5.5--> requiremetns of old 4.1.2.1, 4.1.2.3
New 5.6--> requirements of old 4.1.3

Etc, etc.  Your company will still need to conduct a gap analysis, but I think you will find that you probably can use much of what you have in your existing QMS.

I have been through the transition before. It was not nearly as difficult as I first thought it was going to be. The reference document has an appendix or listing in the back that relates old to new section numbers.
