#2525 – Migration from J!2.5 to J!3

Hi

1 - Depends on what you have to transfer. If this is just about the URLs, then normally you don't need to do anything. Assuming you have kept the same categories and articles titles/aliases, and you use the same settings in sh404SEF, the URLs are just going to be created the same.

If you have custom URLs, they you have 2 look at 2 options: either recreate them manually on the new site, or copy db tables.
If you have custom meta data, then maybe copying the db tables is a good idea.

2 - You can import Aliases using the Import button on the Aliases page. You can start by creating a couple manually, then use the Export button. That will give you a sample of the file format to use, and then you can create the redirects in Excel or a text editor. Note however that if the number of redirects is large, this can be actually more tedious than copy/pasting them in sh404SEF interface, because the Aliases file needs to have the original non-sef URL, which is hard to find and type.

3. Mijoshop

As far as I know there's no plugin for Mijoshop but we are considering installing Mijoshop SEF to manage just the Mijoshop URLs. Do you see any issue with this separation?

You cannot have 2 sef extensions on a Joomla site. It's one or the other, not both.

Hi

1 -

Is this 100% compatible between J2.5 and J3?

The latest sh404SEF for J2 will be compatible, DB-wise, with the current sh404SEF for J3 (don't wait too much, this will change). Now the real question is not about sh404SEF. The real question is about article ids and categories ids and Itemids (menu items ids).
From the description of your process, it looks like those will have changed. If so, it's unlikely the direct transfer will allow matching meta data (attached to the original non-sef URLs) to the new non-sef URLs.
If you have changed content database structure, and thus ids, one way may be to write some SQL code, or PHP to match new ids to old ones. That's rather complicated actually, so must be evaluated against cut/pasting or similar

2 - Not sure now if this can work, for the same reason, change in ids.

3 - Doesn't work like that, each extension will alter the incoming requests, and try to build the outgoing links. There will be interferences.

Hi

Since we are doing a complete overhaul, we've decided to work through the URL's in excel manually and then try to import them in one go.

OK. Just be aware of my remark above, about the ids not being the same. Also, as you probably plan on doing, you surely want to start by testing the process on a few URLs, before jumping all in.

About Mijoshop, if we set in the sh404sef configuration to not manage the Mijoshop component, can we add individual URLs to sh404sef to make the human friendly and add meta data titles and descriptions? We would like to go so for our main category pages.

You can only attach meta data to URLs stored in the database. So if you set Mijoshop to:

- leave as non-sef: no URL in database, no meta data or custom SEF
- Simple encoding: same
- Use Joomla router: same

The only option is to "Use default handler". WHen you do that, a usually good solution is to then set the second option to "Use router.php, with menu item". This is the closest to using Joomla SEF, but still storing items in the database, and therefore being able to customize them or attach meta data.

Hi

Indeed, depending on how the URLs are created, this might generate a lot of URLs in the database. THe only option there is to test, and see how those filters work. If they are working through ajax for instance, there might not be distinct URLs for each filter combination. If the URLs varies with filters, but only a part of it is SEF, and the rest is non-sef ie: /category/filtered?optiona=12&optionb=787&optionc=4545, then there is no problem, because only the SEF part is stored in the DB (/category/filtered).
