Upgrading ABP.io 3.1 to 7.4 - Upgrade or Rewrite? #5959

scottie.tang@cpy.com.hk created 2 years ago

ABP Framework version: v3.1
UI Type: MVC
Database System: MongoDB
Tiered (for MVC) or Auth Server Separated (for Angular): yes

Dear Sir,

We are considering upgrading one of our application from abp framework version 3.1 (MVC+MongoDB) to 7.4 (BlazerServer+Mongo) and would greatly appreciate your expert consultation.

Should we proceed with the upgrade (if possible?) or consider a code rewrite? How compatible is our codebase with the latest version? What effort is required for the upgrade?

Thank you for your support.

Best regards,
Scottie

Hi Anjali,

Thanks for your reply.

From the migration guide, I can see that there are several "version to version" guide.

7.3 to 7.4
7.2 to 7.3
7.1 to 7.2
7.0 to 7.1
6.0 to 7.0
5.3 to 6.0
5.2 to 5.3
5.1 to 5.2
4.x to 5.0
4.2 to 4.3
4.x to 4.2
3.3.x to 4.0
2.9.x to 3.0

So if my application version is 3.1, does that mean i have to go through 3.3.x to 4.0, then 4.x to 5.0 and so on ? May i have some guidance/direction please? thank you.

Regards,
Scottie

Hello scottie.tang@cpy.com.hk,

Yes you are right ; you need to update step by step as 3.3.x to 4.0, then 4.x to 5.0 and so on.

Also have look to this similar issue https://support.abp.io/QA/Questions/5599/Need-Information-on-Abp-Version-upgrade-from-513-to-732
