Subject [jira] Commented: (JSPWIKI-476) Export Tool GUI-Discussion
Date Wed, 04 Feb 2009 20:11:59 GMT


Harry Metske commented on JSPWIKI-476:

Let me describe a possible migration scenario:

1. You have your good old wiki running with a classical repo
2. You have installed and configured your brand new and shiny JCR based wiki
3. Then you want to test this new thing and use your existing data
4. You go to your Exporter running in the old wiki and export everything, you don't need any
locking or whatsoever 
5. Import the xml file into the new JCR wiki, and test a lot
6. you probably repeat 4,5 a couple of times.
7. you finally reached the point that you are confident the new wiki works fine, and you want
to switch over
8. you then do a final export
9. now you have to be sure that your users don't edit any pages anymore in the old repo, either
by a lock, or by just stopping the old wiki
10. do your final import and redirect your users to the new wiki

If you can afford downtime this scenario is just fine, and you probably don't need locking.
If not, you might need a time-slot where your wiki is in RO-mode, while you do your final
export/import, and eventually (network)switch to your new wiki or something like that.

I am very biased by my daily work working with financial/transactional systems, so maybe Janne
is right and we should start with no locking at all, or  just give some error messages during
export telling that you are exporting locked pages.

Let's keep it simple in the first place, we can always make things more complicated in the
future :-)
