When I move bot from perl-5.30.0 to perl-5.32.1 I encounter with BDB0091 DB_VERSION_MISMATCH error And it looks like I have to export essential data on older perl to some portable format and then import it on newer perl environment.

Migration procedure.
|
|
|
|
When you require to perform this procedure?
|
|
- When perl version is changed
|
|
- When migration to other OS or distribution occurs
|
|
|
|
Why do i have to perform this procedure?
|
|
- Some modules are vendored with bot
|
|
- BDB can vary its on-disk format depending on dbd version that linked with
|
|
perl interpreter itself and its apropriate module.
|
|
|
|
How can i guess that i miss to perform this procedure?
|
|
Most notable sympthom is 'BDB0091 DB_VERSION_MISMATCH' in logs and bot admin settings are lost.

Procedure steps.
|
|
|
|
On source system perform following steps:
|
|
1. stop the bot, to unlock and close all files.
|
|
2. make a backup
|
|
3. prepare target system and copy bot to target system
|
|
|
|
On target system perform these steps:
|
|
1. remove vendor_perl dir in bot' directory
|
|
2. run "bash bootstrap.sh" (no quotes) and wait until it suscessfuly build and
|
|
installl required modules.
|
|
3. run perl bin/cache_import.pl script. It should create cache and exit
|
|
silently.
|
|
|
|
Now it is possible to run bot without settings loss.
