Hi Dave,

I do an upgrade for every version (4.7.0 > 4.7.1 > 4.7.2, .... just all the way up to 4.9.1)

Also be sure to carefully read the upgrade instructions on Codeplex. Especially when upgrading from 4.7.2 to 4.8.0 and from 4.8.1 to 4.9.0.

A tool that also comes in really handy for merging your .config files when upgrading to 4.9.0 is Winmerge: http://winmerge.org/

Hope this helps,

Anthony

Hi guys,

Thanks for the input.

I think I will upgrade locally from 4.0.x -> 4.5.2 -> 4.7.2 -> 4.9.1

I will keep track of database / config changes so I can upgrade the production manually.

Cool, let me know how it went. Maybe I'll also skip some upgrade versions in the future :) 

I'll just upgrade to every upgrade release out of precaution (except for minor minor upgrades like 4.7.1.1)

If you're using uComponents 4.x, it breaks from 4.8.0 onwards: Upgrading to Umbraco 4.8.0 breaks support for uComponents

An issue that has been solved with uComponents 5.x

greetings,

Anthony

Hi guys

I'd just like to add that some minor db changes was made in the 4.8.1 release. Can't remember the impact but maybe it's something to be aware of before cutting corners and skipping some versions in the process.

Just my 2 cents.

Those db changes should also get executed when upgrading to a version higher than 4.8.1, right?

I believe it's fair to expect that...but must admit that I'm not sure they are. Think it's better to be safe than sorry and do all the steps. 

But hey, that's just me - a guy who likes to wear a seat-belt ;-)

I have recently upgraded a site from 4.0.4.2 -> 4.9 and it was pretty painful.

After a number of failed attempts to go 4.0.x -> 4.5.2 -> 4.7.2 -> 4.9.1 I had to admit defeat adn run through every step of the process which seemed to work better.

There are a few gotchas along the way so make sure and read the release notes carefully.

is working on a reply...
