Among sites I manange there are two which are still running very old installations:
- Mambo 4.5.5 Stable
- Joomla! 1.0.15 Stable
There was no practical need of migration last years, they have only minor content updates, they run stable having almost no extensions and the only active user is administrator.
I understand migration of their content might need more than one phase but I'm fine with that. Could you please help me with drawing the upgrade path? I think Mambo should be taken first to J! 1.0, then both 1.0 sites to J! 1.5 and then both to 2.5/3.X. Correct?
Content I'd like to preserve – only core-related stuff:
- articles (static content items and standard content items) [about 200]
- categories (/sections) [about 50]
- menu items [about 50]
- web links [about 30]
- content of custom HTML modules [about 15]
Is semi-automatic migration viable or should I think of copy-paste manual work as of faster and less painful solution?
