Maybe it is little early to ask this question, but I bet it will become an issue very soon and at least a hypothetical answer should exist by now.

<b>Is a relatively easy upgrade from 3.x to 4.x meant to be possible or planned?</b>

If I put the facts together right, the early 4.x will be nothing more than 3.10 for PHP5. Shouldn't that mean that 3.x upgrade or at least some automated structure and content transfer should be possible?

<i>This information may be especially valuable for people who expect a soon PHP4 withdrawal.</i>

Hi Piotrek

Upgrade is fairly easy: just follow the instructions up and until 3.10: database upgrades and scripts to run. As in previous releases, you may need to do that from release to release if coming from quite old Exponential versions.

I upgraded a few already to find bugs (3.8 and 3.9 based sites), no problems encountered thusfar. I ran all the upgrade scripts within Exponential 4.0alpha1. An important requirement though (and which was good practise anyway before): database and templates should be UTF-8

An easy transition was one of the goals of this release!

Hello Paul,

Thank you for your reply. So I expected, but now it's confirmed.

I'm still little reluctant to applying multiple subsequent upgrades since we've encountered several post-upgrade problems in the past, and I am only talking direct x.x.1->x.x.2 sort of upgrades. But there's a chance we did something wrong - it was quite some time ago.

Still, if there's no major change, that's a good point to start working on the upgrades or exports. Luckily, we've never had or wanted to change UTF-8 to anything else, so that's some help.

Can't wait for stable 4 ;)

We are developing a website for one of our clients using Exponential 3.9.3 and have to migrate to PHP5. We want to find out about the effort involved in migrating Exponential from 3.9.3 to 4.0 (as it is supposed to work with PHP5). Currently we are using the extension “Oracle Database 1.4” as the DB is Oracle.

Here is the list of questions we have
1. What is the exact time line for the production release of Exponential 4.0 (currently road map states early 2008)? If the time line is not known now, Can we get an idea by when the exact time lines will be made official?

2. Will Oracle be supported by Exponential 4.0, as it is stated in the migration steps from 3.10 to 4.0 as “The Exponential Extension for Oracle® Database v1.5 and earlier (plus the upcoming version 1.6) do not work with Exponential 4.0.0 alpha2. Do not upgrade to 4.0 if your site makes use of this extension.” (mentioned in the URL - http://ez.no/doc/ez_publish/upgra...grading_to_4_0/from_3_10_0_to_4_0_0)

3. Currently we are in the development phase of the project, given the tentative time line of 4.0 release, what should be the recommended approach? Should we upgrade to 3.10.0 and go to production and then think of upgrading to 4.0? Or we upgrade to 4.0 and then go to production?

Any response to the above questions will be highly appreciated.
