There should be nothing that you have to do manually, unless the 
UPGRADE.txt file tells you otherwise.

Since you're skipping so many major versions, though, it becomes hard to 
see where the problems originate. Since the upgrades also include more 
than one Zope migration, it may be that this will not work in one fell 
swoop. (I know that Zope 2.8 internally migrated some index objects for 
instance, but that could be circumvented by manually rebuilding the 
index after the process.)

To see what causes problems, the event log might be a good place to 
start, since the more invasive upgrades tend to log what they're doing. 
If that doesn't result in any clues, the only recourse may be to go 
through the upgrades for each major version, instead of doing the 1.4 to 
2.0 all in one, to see which individual upgrade results in the problems.

Some clues:

1.6 to 2.0 is a 'dummy' upgrader: it doesn't really do anything.

1.5 to 1.6 seems to be the only place where anchors are touched, (for 
index items), so this may be your best bet.

 From 'what's new in Silva 1.6':

"""
Anchors and index items

Silva 1.6 has a change in the index items to make them conform to the 
XHTML spec. In short, you now have anchors, and you have anchors with 
titles which makes them index items. If you want your anchor to show up 
in the Indexer, give it a title when editing. See an illustrated 
explanation in the documentation:
http://www.infrae.com/products/silva/docs/author_basic/kupu_content_editor#Links_to_named_anchors54

Silva 1.6 requires a minor upgrade for this feature. The upgrader will 
change all existing index items to XHTML valid anchors with a title. 
Many existing index items contain illegal characters, e.g. "Links to 
named anchors" has spaces. The upgrader will change the illegal 
characters to underscores, which will render so:

<a class="index-element" id="Links_to_named_anchors"></a>

In Kupu the anchor will have a title with spaces: "Links to named 
anchors". This is used in the Indexer as the text for the link display. 
If there are other illegal characters in your index items, they'll all 
become underscores, e.g. "Fermer items publiés" will become 
"Fermer_items_publi_s".
