I had tried a couple of other extensions and strategies for converting a site from 1.5 to 1.6 and I bought sp-upgrade based on reviews here. After a few false starts, the extension worked almost 100%.



Migration from 1.5 to 1.6 is not trivial but this extension comes close to making it so. I had three tries at migrating my first site. Initially, I had permissions issues. Next there were problems with some section and category names which needed fixing on the 1.5 site and then finally bingo! Everything across.



My recommendation would be to get a clean, empty, 1.6 installation with sp-upgrade installed, and then zip up a copy before working as a backup because you may not get things right first time. If the migration does not work as planned, scrap everything and start again from the backup. The migration only takes a minute so starting again is a quicker option than fixing everything with edits.



Another small quirk with this version is that if the migration aborts for some reason (permissions for example) you are not given a full warning.



Anyway, sp-upgrade works well and makes a difficult task simple.

This component is very efficient and easy to use. I also appreciate the fact that it's absolutely safe to use since it doesn't interfere with your Joomla 1.5 installation at all (just reading from it).



I had one single, but very important menu problem that I wasn't able to solve myself, and neither was anyone else (template provider for example).



However, I turned to Panayiotis (SP Upgrade developer) who investigated and solved the problem even though it had nothing to do with his component. It was in fact a template problem!



This was all done in one day and Panayiotis fixed the problem + he explained it to me in a very kind and pedagogical manner so that I was able to understand.



I also tried other solutions for migrating before this one but SP Upgrade will be my permanent choice from now on. That's for sure!

After downloading I had some trouble running this mod. But an email to the author did the trick. I'm astonished by the support the gave me. And in the end it's probably a bug in Joomla! 1.6... (you MUST choose "MYSQLi" and not "MYSQL" during installation of J16!)

Many thanx to CYEND.

The extension didn’t work because I had a large number of menu’s and articles. I contacted the support and the fixed it one day. The solve the problem and updated the component so it should even work for large sites.



Huge time saver. Thanks.

Did not work at first but I had great support within the day and everything went smoothly.

The great thing is that you keep your old ids meaning your Google Rank. Some menu links were broken but manually I fixed

no error, but nothing in new database ! this component doesn't work for me...
